The Tsukuba AMS system is able to measure environmental levels of long-lived radioisotopes of 14C 26Al 36Cl and 129I by employing a molecular pilot beam We have focused our activities on 36Cl measurements In 2009 309 samples for 36Cl were measured by the Tsukuba AMS system Total operation of the Tsukuba AMS system was 54 days in 2009 Table 1 shows current research programs and the number of samples in 2009

We have measured cosmogenic 36Cl in the Dome Fuji ice core Antarctica The apparent 36Cl flux at the Dome Fuji Station was estimated approximately to be 25ndash35 times 104 atoms cmndash2 yrndash1 [1] We have started a new project for 36Cl measurements in the Greenland NEEM ice core It is expected to discover innovative bipolar information for the paleo-environmental reconstruction We have carried out a joint research project for 36Cl exposure dating of Tiankeng in China with the China Institute of Atomic Energy We have been developing a 41Ca AMS for future research programs 41Ca is a cosmogenic nuclide of interest for studying the irradiation history of extraterrestrial material

13 The developments of detectors of the particle identification for RIbeam experiment

TMoriguchi AOzawa HSuzuki DNagae Y Ito HOoishi Y Ishibashi KYokoyama NKamiguchi

and YAbe

We have developed a solid-neon detector for measuring the total energy of particles in the RI beam

experiments The value of total energy of each particle is needed for particle identification of the RI beam

An NaI(Tl) detector is usually used as the total-energy detector This detector is unsuitable for high-rate

beam because of the scintillation light quenching It is important to develop a new total-energy detector

which replace the NaI(Tl) detector

Through the interaction of radiations with noble gasses scintillation is emitted and electronminushole

pairs are produced From these features the noble gasses can be used as the scintillation counter and

the ionization chamber While the liquidsolid xenonargon detectors have been studied [1] there are few

studies of the liquid or solid neon detectors One of the reasons is that it is difficult to make a liquidsolid

neon because the melting point of the neon is lower than that of the xenonargon To solidify the neon gas

we used a cryogenic system which have been already used for developing a solid hydrogen target [2] The

purpose of this study is to investigate the properties of a neon as a scintillation and a proportional counter

and to develop this detector system

The experiment have been performed at the F-course beam line in UTTAC Figure 1 shows a schematic

view of an experimental setup and a picture of the solid neon cell A proton beam with 21 MeV was

transported to the neon detector located downstream of the Q-D-Q magnets The beam intensity was

adjusted about 1000 counts per second by scattering with a gold foil at the scattering chamber The size of

the solid neon was φ50 mm times 30 mmt For using as a scintillation counter a photo multiplier tube (PMT)

was equipped for detecting the scintillation The wave length of the scintillation from the solid neon was

shifted by using a tetraphenyl butadiene (TPB) for being detected by PMT For using as a proportional

counter the copper wire which was applied a high voltage was put in the solid neon for obtaining the

signals

In this experiment no signal from the solid neon was observed by using both counters We are finding

out the reason about the present result

We are developing two types of active targets using Gas Electron Multiplier (GEM) [1] for the experi-

mental study with intense (106minus7 Hz) radioisotope beams in inverse kinematics The active target has two

functions of target and detector at the same time and enables us to measure the recoiled particle with low

energy

One type being developed is ldquobeam transparent typerdquo for the study of nuclear structure and property

of nuclear matter by measuring the giant resonances such as monopole dipole and Gamow-Teller ex-

citation via (αα prime) (dd

prime) or (d2He) reactions Missing mass spectroscopy is a powerful tool for these

measurements since such resonances are populated with high excitation and then the excited nuclei de-

cay immediately by particle emission Hence we need to measure the recoiled particles such as α d and

protons with low kinetic energy in the forward angle scattering which is essential to identify the transfer

momentum in the reaction The structure of this active target is optimised as not to measure the beam

particles for the high-rate beam up to 107 Hz with the high incident energy of 100minus200 MeVu The

detail of the structure is described later

The other type is ldquobeam measurement typerdquo for the study of nuclear astrophysics especially rp-

process in nucleosynthesis So far the (α p) reaction has been measured by using thick-target method in

CRIB facility in RIKEN Although the large window of excitation energy is studied at the same time by

this method there still remain some uncertainties in identification of reaction process beam energy and

position of beam and recoiled particles To reduce these uncertainties we need to measure the reaction

point

We performed two experiments to evaluate the energy and position resolutions of active targets and

their position dependencies for ldquobeam transparent typerdquo in December 2009 and for ldquobeam measurement

typerdquo February 2010 In this report the details of ldquobeam transparent typerdquo active target the experimental

setup and result are described

The schematic view of the ldquobeam transparent typerdquo active target is shown in Fig 1 In this figure the

typical case of physics experiment is shown which is not the same as the setup in this experiment The

beam particles go through between two field cages to measure recoiled particles The electrons created by

the recoiled particles in the cage drift along the electric field formed by doubly layered field wires The

electrons reach at the GEM of 100 microm thickness and amplified by typically 103 The charge is collected

by a readout pad patterned with 1645 times 1645 mm2 rectangular triangle Since there is no field along the

beam path and the centroid of cross section of beam is away from field cage the electric field in the cage

is not affected by the space charge of the residual ions Three dimensional position is deduced from the

drift time and the charge division in two adjacent pads

Fig 2 Resolutions from the charge division (top left)and the drift time (top right) and their position depen-dencies Energy resolution (bottom left) and defini-tion of incident position

The experiment was performed at the 12UD Pelletron tandem accelerator Ion beam of 4He was

accelerated up to 30 MeV The beam rate was adjusted to be typically 103 Hz by using gold-foil scatterer

The beam was irradiated from the side of the field cage ie the detection area was bombarded directly

by the beam particle The active target was filled with an admixture gas of He (95) and CO2 (5) of

atmospheric pressure and operated with 700-Vcm electric field where drift velocity of electron was about

2 cmmicrom A voltage supplied to the GEM was adjusted so that gas gain was about 103 The signal from

the active target was amplified using RPA-211 (REPIC) and digitized by 100-MHz sampling flash ADC

SIS3301 (SIS) Trigger of the digitization was made by the logical OR of first 4 pads along the beam path

Time and charge information are deduced by the pulse shape analysis of the sampled signal First

analysis has been done with simple way the timing information is deduced from the extrapolation of rising

edge and the charge information is deduced from the maximum charge assuming rise and fall time of each

pulse are similar Their position dependence are shown in Fig 2 The ordinate and abscissa axises show

the resolution and incident position with the origin at the center of the pad respectively The resolution

from the charge division strongly depends on the incident position however its dependency is explained

by propagation of errors of the energy deposition in two pads On the other hand the resolution from the

drift time is independent from the incident position The measured position resolutions are typically less

than 700 microm and 80 microm from the charge division and the drift time respectively The calculated angular

resolution is about 8 mrad

As outlook we plan to measure the effect of δ rays with high-energy (sim200 MeVu) beam and the

distortion of electric field by the space charge with high-rate (sim106 Hz) beam

Classical novae are stellar explosions resulting from a thermonuclear runaway which occur in close

binary systems consisting of a compact white dwarf and a low-mass Main Sequence companion The

dominant nova nucleosynthetic path followed by the thermonuclear runaway can be understood by ana-

lyzing the Si isotopic abundance ratios (29Si28Si and 30Si28Si) in presolar grains of nova origin which

are dust grains formed in the ejecta of classical novae [1] This in turn can help to elucidate the chemical

composition of the white dwarf and the thermal history of the white dwarfrsquos convective envelope

To calculate the Si isotopic abundances in such presolar grains one needs to know the rates of the re-

actions which affect the 2930Si production and destruction in novae One such reaction is the 29P(pγ)30S

reaction [2] whose rate depends significantly on the properties of 30S resonances above the proton thresh-

old of 30S at Sp = 4399 plusmn 3 keV [3] However the properties of these resonances are yet not well

understood

At the temperatures characteristic of explosive hydrogen burning in novae (01 ndash 04 GK) the 29P(pγ)30S

reaction rate is dominated by two low energy 3+ and 2+ resonances whose energies were predicted to be

4733plusmn 40 keV and 4888plusmn 40 keV respectively [2] Despite several experimental studies on the structure

of 30S [4 5 6 7 8 9 10] the 2+ level remains unobserved and the 3+ level has only been tentatively

observed to be at 4704plusmn 5 keV recently [9] Thus the 29P(pγ)30S reaction rate which depends exponen-

tially on the resonance energies remains uncertain by orders of magnitude

In order to address the remaining large uncertainty in the 29P(pγ)30S reaction rate we decided to

further investigate the level structure of 30S using the 28Si(3Henγ)30S reaction The first phase of this

in-beam gamma-ray spectroscopy measurement was performed at UTTAC A natural Si target of 25 microm

thickness was irradiated by a 10 MeV 3He beam Gamma-gamma coincidence measurements were per-

formed with two Ge-detectors with relative efficiencies of 140 and 70 A NE-213 liquid scintillator

was also employed to detect neutrons for a measurement of neutron-gamma coincidences

Due to low neutron statistics in this first run we could not learn much from the neutron-gamma co-

incidence measurement However as a result of the preliminary analysis of gamma-gamma coincidence

measurement we were able to observe eight levels in 30S three of which are above the proton threshold

including the two levels at 46879 plusmn 02 keV and 48104 plusmn 05 keV which likely correspond to the two

9

astrophysically important states predicted by Iliadis el al [2] Moreover a state was observed at 42501

plusmn 14 keV which is below the proton threshold and might be a new state in 30S The origin of the newly

found level is still under investigation but it decays to the second excited state of 30S by emitting a 8454

keV γ-ray (see Fig 1) If one compares the γ-decay scheme of 30S with that of its mirror nucleus 30Si

one can tentatively estimate the spin assignments of the levels in 30S from the relative intensities of the

γ-rays This analysis is still in progress In order to pin down the spinparity assignments the next phase

of the experiment will measure the Directional Correlation of Oriented (DCO) nuclei ratios of the relevant

transitions

22 Measurement of nuclear magnetic moment of unstable nucleus 40Sc Ⅱ

YIshibashi AOzawa TNagatomo1 YTagishi YAbe YIto HOishi NKamiguchi HSuzuki DNagae TMoriguchi and KMatsuta2

The unstable nucleus 40Sc(Iπ=4- T12=182ms) is located near stable nucleus 40Ca which is a doubly closed shell nucleus Thus its nuclear structure is interesting However the nuclear magnetic moment (micro) of 40Sc has never been measured Since micro is sensitive to the configuration mixing in the nucleus we started the measurement of 40Sc from the last year

Last year we measured only micro of 40Sc in CaF2 crystal But we did not get the central value of micro of 40Sc [1] So we did three improvements First we measured micro of 20F in CaF2 crystal for the system check Production of polarized 20F by polarized deuteron beam was performed at UTTAC previously [2] Second

we changed β-NMR system to improve signal-to-noise ratio (SN ratio) Therefore to the previous system we added thick scintillation counters (10mm thickness) for measurement of energy spectrum of β-ray and changed chamber material from Al to Delrin as shown in Fig1 At last we changed target from CaF2 to

CaO Because micro of 41Sc (Iπ=72- T12=059s) has been measured in CaO crystal [3] so we can expect that nuclear polarization of 40Sc is maintained during its half-life We made CaO target at RIKEN First we

made CaCO3 pellet from CaCO3 powder Next the pellet was put into oven and baked at 900degC through one night As a result CaO is made from CaCO3

Fig2(c) From these figures we calculated purity of 40Sc at condition (a) (b) and (c) respectively 60plusmn2 72plusmn1 and 76plusmn1 So we recognized that condition (c) is best and determined to measure in CaO target in future Fig3 shows NMR spectrum of 20F Red (green) points are data that beam polarization direction is up

23 Measurement of nuclear magnetic moment of unstable nucleus 30P YAbe AOzawa HSuzuki YTagishi YIshibashi YIto HOoishi DNagae TMoriguchi KYokoyama TNagatomo1

The magnetic moments of the nuclei are suitable to investigate the nuclear structure The unstable

nucleus 30P (half life T12=2498 min Iπ=1+) is the self-conjugate nucleus where the isospin is zero The nuclear magnetic moment of 30P has not been measured We measured yield and purity of 30P to optimize the beam condition

The unstable nucleus 30P were produced through the 30Si(pn)30P or 29Si(dn)30P reaction initiated by the beam of proton or deuteron obtained by 12UD Pelletron at Tandem Accelerator Complex University of Tsukuba A 8910 MeV proton beam and 45 MeV deuteron beam irradiated natural Si (28Si29Si30Si = 9223467310) target The intensity of proton beam was ~6 nA deuteron beam was ~5 nA The

target was single crystalline Si 10 mm thick All the 30P nuclei were stopped in the same Si target The β rays from the 30P nuclei in the target were detected by two sets of plastic scintillation counters located above and below the target These counters consisted of two plastic scintillators with a thickness of 10 mm

A typical time spectrum of β rays is shown in Fig1 The spectrum is fitted by two exponential functions The 30P nuclei was produced however 29P (T12 = 4142 s Iπ=12+) nuclei was also produced We calculated a value of Figure of Merit (FOM) that is defined by FOM = YP2 where Y is yield P is purity FOM should be as large as possible Table 1 shows FOM for all experiment conditions The best

The polarized 29P was produced through the 29Si(drarr

n)30P reaction initiated by the polarized deuteron beam (P=75) A 4 MeV deuteron beam irradiated natural Si target The intensity of polarized deuteron beam

was ~25 nA The target was single crystalline Si with 05 mm thickness All 29Prarr

nuclei were stopped in the same Si target The β rays from the 29P nuclei in the target were detected by three sets of plastic scintillation counter located above and below the target where one set of plastic scintillation counters with a thickness of 10 mm were added To keep nuclear polarization of 29P inside the target a static magnetic field H0 (~19 kG and ~37 kG) was applied To perform NMR a radio-frequency (RF) magnetic field H1 (~355 MHz and ~695 MHz) was applied by a Helmholtz coil We measured NMR spectra with two conditions Observed NMR spectra are shown in Fig2 and Fig3

AP shown in Fig3 is larger than AP shown in Fig2 where A is asymmetry parameter of β-rays P is polarization Thus the static magnetic field should be raised as much as possible We will develop the system which can supply higher static magnetic field After the development we will perform the magnetic moment measurement of 30P

24 Study of nuclear synthesis of 26Al by gamma ray spectroscopy III T Komatsubara Y Sugiyama A Ozawa Y Abe N Kamiguchi K Yokoyama T Shizuma T Hayakawa S Kubono JAEA CNS Tokyo University Since observation of 1809-MeV gamma rays by satellite gamma ray telescope has been reported[1] the

astrophysical study of 26Al is very important for nuclear synthesis Half life of the 26Al is 72times105 year The nucleus 26Al can be created by 25Mg(pγ) reaction However there is bypass reaction sequence 25Al(pγ)26Si(βν)26mAl(βν) which emits no gamma ray of 1809-MeV The excited states of 26Si key nucleus have been studied by reaction mechanism[2-5] and gamma ray spectroscopy[6] In our previous studies one new level is found above proton threshold at 5886-keV in the 26Si[7] For the determination of spin of the observed state gamma-ray angular correlation measurements were carried out[8] In order to investigate the level structure in 26Si in-beam gamma ray spectroscopy was performed at

UTTAC The excited states of 26Si were populated by the nuclear reaction 24Mg(3Hen)26Si The 3He beam of 10 MeV was irradiated on a natural Mg target Target thickness of the Mg foil is 3 mgcm2 Gamma-gamma coincidence measurements were performed by using Ge detectors Relative efficiencies of the Ge detectors are 40 and 35 at 1333-keV In the previous angular correlation measurement there was a uncertain parameter of normalization which used for correction of different solid angles of the detectors In order to conserve the solid angles of the Ge detectors a goniometer of 15 m in diameter was newly installed in the present study For the measurement of the DCO ratio [9] one detector is fixed at 90 degree and other is mounted on the turn table of the goniometer to move between 90 and 135 degree with respect to the beam axis As the results of the DCO measurement the ratios are shown as crosses in Fig 1 as a function of the gamma ray energy The gate gamma ray is 1797-keV 2+ rarr 0+ transition In this figure previous results are shown as closed circles and theoretical expectation values are also shown as open triangles

For the 989- 1537- 1960- and 2340-keV transitions newly measured values are consistent to the previous results Statistical error of the 2646-keV transition is quite large for the new result For the3875- and 4089-keV DCO ratio can not evaluated in the new measurement because of the small efficiencies of the Ge detectors

Because the new results with goniometer are rather consistent with previous results evaluation of the normalization factor for the previous measurement is confirmed

31 Electron emission from surfaces bombarded by MeV atom clusters

H Kudo H Arai S Tomita SIshii and T Kaneko1

Pronounced suppression of electron emission from surfaces bombarded by fast clusters is one of the

well known vicinage effects [1] However the main mechanism of the suppression still remains unsolved

We report on the recent analysis of the experimental data obtained at Tsukuba [2 3] from which we

conclude that the interference of wake potentials generated by the cluster atoms disturbs the escape of

electrons which gives rise to the observed suppression of electron emission [4 5]

Figure 1 shows the energy spectra of low-energy electrons emitted from KCl(001) and highly-oriented

pyrolytic graphite (HOPG) which were bombarded by C+n beams of 125 keVu (015 MeVatom) For

a measured energy spectrum the integrated yield Yn per nndashatom cluster is given by the area under the

spectrum taking into account the energy dependence of the energy acceptance Figure 2 shows the YnY1

vs n plots obtained from the present experiments for HOPG and KCl targets where we see the typical

linear n dependence Similar results have been obtained also for 417 keVu Cn The observed values of

the slope α (see Fig 2) lie in the range 02 lt α lt 04

MeVatom) Note that the real zero-energy corresponds to 30 eV on the horizontal axis The yieldsare shown for the same number of incident C atoms

The observed n dependences of YnY1 for KCl and HOPG are very similar although Y1 for KCl is

higher than for HOPG by a factor of sim10 (Fig1) Also the difference between the two targets is much

smaller than that in the case of suppression from YnY1 = n These results provide clear evidence against

the possible effects associated with the surface transmission of electrons nor with the track potential

From the analysis of the linear n dependence of electron yield we have specified the possible mecha-

nism of suppressed electron emission from surfaces bombarded by fast clusters Actually the suppressed

electron emission for cluster bombardment is predominantly caused by the disturbance of the electron

escape due to the electric potential generated by moving cluster atoms This model accounts for the ob-

served n dependence of electron emission and long-range interaction of dissociated cluster atoms in the

electron transport process

There is a possibility that the interference term which appears in the expression of wake potential

[6] gives rise to a shift from suppressed emission to enhanced emission of electrons as cluster speed

increases corresponding to that in the case of cluster stopping power However the applicability of the

present model to enhanced electron emission for fast clusters in a Bethe stopping region requires careful

further study

32 X-ray absorption spectroscopy of Mg-Ni and Mg-Ti hydride D Sekiba K Shiba Y Watahiki Introduction The Mg-based alloys such as Mg-Ni Mg-TI Mg-Fe etc have attracted much attention as typical

materials for the purpose of hydrogen storage In order to develop the better hydrogen storage

materials the understanding of their electronic structures is important So many experimental [12]

and theoretical [3-5] efforts have been devoted to this field Interestingly these Mg-based alloys

show the metal-insulator transition by absorbing hydrogen For example the thin Mg2Ni film (50

nm) deposited on a glass substrate is reflective metal while Mg2NiH4 is reddish transparent

semiconductor However the mechanism of this metal-insulator transition has not been elucidated in

terms of the electronic structure We have been trying the in-situ X-ray absorption spectroscopy

(XAFS) of Mg2Ni and Mg2Ti thin film in air and also hydrogen atmosphere

Experimentals The Mg2Ni and Mg2Ti film (200 nm thick) were deposited on the both sides of kapton films of 125

microm thick The films were caped by 5 nm thick Pd layer to avoid the oxidation and enhance the

dissociation of hydrogen molecules For the deposition we used DC magnetron sputtering system in

MANA foundory in National Institute for Materials Science The exact compositions of the prepared

alloys were determined by Rutherford back scattering (RBS) at the C-course of Tandetron

accelerator in UTTAC We newly designed a sample holder suitable to the hard X-ray absorption

spectroscopy with the fluorescent mode in the hydrogen atmosphere (see Fig 1) The both

X-ray-absorption near-edge structure (XANES) and Extended X-ray-absorption fine structure

(EXAFS) were measured at BL7C in Photon Factory in KEK

Results and Conclusion Figure 2 shows the XANES spectra taken at the Ni K-edge on the PdMg2Nikapton film The black

line indicates the initial state before the hydrogenation We can see the shoulder-like features at

83165 and 83225 eV and a peak at 83408 eV These spectral features are consistent with the

previous peport [1] taken by transmission mode and total fluorescence yield mode After the dosage

of Ar 98 + H2 2 gas with the pressure of 015 MPa in the newly made sample holder the

spectrum changed slightly (red line) The edge position shifted toward the higher photon energy

However this shift is much smaller compared with that reported in the previous paper [1] We

changed the sample gas to the pure H2 then we obtained the spectrum plotted by green line There

we observed the edge shift with ~ 1 eV and the peak at 83408 eV remained at the same energy

These are consistent with the previous results Thus it was confirmed the verification of our new

sample holder and the sample preparation methods As a next step we applied the same method for

the Mg-Ti alloys for which no comprehensive study of XAFS have been made

33 The vicinage effect on energy loss of C+2 in a thin carbon foil

S Tamura S Tomita Y Narita H Tanikawa K Kurita S Isii K Sasa and H Kudo

When swift molecular ions are injected on a thin carbon foil the energy loss of constituent individual

atoms differ from the case of mono atomic ion injection This effect is known as one of the vicinage effects

which was first reported by Brandt et al [1] in 1974 Since then many experimental results were reported

for carbon clusters [2-4] For an injection energy higher than 20 MeVatom it is shown that the vicinage

effect is constructive namely the energy loss per atom for cluster ions is larger than that of an atomic ion

(∆E(C+n )n gt ∆E(C+)) The results can be reproduced with the calculations based on the interference of

response of the target electrons [5 6] However in the low energy region below 1 MeVatom Kaneko

[5] predicted the destructive effect while Heredia-Avalos et al [6] reported constructive effect in the

calculations For the low kinetic energy below 1 MeVatom there have been only two reports so far [3 4]

The experimental results reported by Brunelle et al [3] show the destructive effect while Tomaschko et

al [4] show slightly constructive trend In both cases the uncertainty is too large to discuss such a small

effect In the present report we performed the precise measurements of energy loss of C+2 in a thin carbon

foil in the energy range from 033 to 066 MeVatom

Schematic drawing of the experimental setup is shown in Fig1 The thin carbon foil whose thickness

is 33 microgcm2 was mounted on a mechanical system together with empty frame which moved periodically

so that carbon molecular beam penetrated the thin carbon foil and empty frame alternatively Subsequently

the energy of carbon atoms that elastically scattered by Au on a amorphous carbon foil were measured at

100 by an ion-implanted-silicon charged-particle detector The measured energy is proportional to the

incident energy on Au target so that the energy of carbon atoms after penetration through the thin carbon

foil can be measured

values are in agreement with theoretical calculations [5] The reversal of the effect seems to take place

34 Study on nitrogen diffusion in ε-Fe2minus3N submicron particles

M Minagawa H Yanagihara M Kishimoto and E Kita

Iron nitrides have been attracting much attention as magnetic materials because of their unique prop-

erties such as large saturation magnetization large magnetic anisotropy[1 2] and high corrosion resis-

tance Additionally their compound are only composed of non-rare elements and have high potentials as

environmentally-enhancing materials being alternatives of current high performance magnetic materials

including rare metals such as FePt and NdFeB

Iron nitrides are categorized to be interstitial compounds and the crystal structure depends on the

nitrogen content and magnetic properties also change The typical iron nitride are αrdquo-Fe16N2 (bct) γrsquo-

Fe4N (fcc) and ε-Fe3N(hcp) that are ferromagnetic at room temperature

The ε phase Iron nitrides are stable and the nitrogen concentration varies from 25 at to 33 at cor-

responding to the nitrogen concentration of x 0lexle1 for ε-Fe3minusxN The phase posses superior corrosion

and mechanical properties and were well studied[3] The magnetic properties in the phase were reported to

be largely influenced by the nitrogen concentration Curie temperatures and magnetic moments decrease

drastically with the increase of nitrogen concentration[4]

It is important for these nano-structured iron nitrides to elucidate fundamental properties in order to

use as new types of magnetic materials To clarify that fundamental physical and magnetic properties bulk

samples are preferable however bulk synthesized by usual methods will have a nitrogen concentration

gradient On the other hand nano-sized particles can be crystallized in a single phase nitride much easier

than bulk Because they have a large surface area nitrogen atoms can penetrate easily and uniformly into

the particles Extending the size of the particles with in single-phase it is possible to make an accurate

characterization with the small surface effects

In this study we used 180 nm Fe3O4 particles with relatively large size as starting material and syn-

thesized single phase ε-Fe2minus3N The use of large particles has an advantage that the influence of surface

oxidization can be suppressed By annealing in H2 atmosphere nitrogen concentrations were varied and

were deduced from the lattice parameters Nitrogen diffusion is discussed supposing the uniform distri-

bution of nitrogen atoms in particles

180 nm Fe3O4 particles were used as starting materials and were reduced in H2 flow at 673 K to 25

h Reduced samples were nitrided in NH3 flow for 24 h at various temperatures Then we obtained the

optimum temperature at which single-phase ε-Fe2minus3N can be generated The backward growth of the

sample decraesing the nitrogen concentration was achieved by annealing the samples at 603 K in H2

flow with varying annealing time A usual backward growth procedure is done by the annealing in the

gas mixture of NH3 and H2 at lower temperature than the nitriding temperature[3] however we used H2

atmosphere X-ray diffraction (XRD) was carried out for identification of resulted phase and determination

of lattice constants

Mossbauer spectra were recorded at room temperature Data were numerically analyzed with a com-

mercially available fitting software MossWin ver3 Samples for Mossbauer spectroscopy were sealed in

plastic capsules with epoxy or vanish to prevent the oxidation

Samples reduced from the Fe3O4 particles were confirmed to be in an α-Fe single phase Nitrided

sample at temperatures around 623 K showed ε-Fe2minus3N single phase Especially the sample nitrided at

623 K was sufficiently nitrided therefore the sample is labeled as rdquoas-nitridedrdquo(a) Figure 1 shows XRD

patterns and the as-nitrided sample revealed to have the hcp structure with larger unit cell than that of bulk

ε-Fe3N This result inferred the excess nitrogen atoms enlarged the lattice Its lattice constants are a =

0480 nm and c = 0443 nm Nitrogen concentration x in ε-FexN was reported to have a relation between

lattice constants of a hcp structure as follows[4]

x =00673

aminus044709=

00318cminus042723

(1)

Then x for the sample (a) was estimated to be 20 and nitrogen atoms are packed up to the limit of hcp

structure The sample annealed in H2 flow for 2 h has lattice constants of a = 0473 nm and c = 0439

nm and the chemical formula was ε-Fe26N The sample with 4 h annealing (c) had the lattice constants

identical to the bulk ε-Fe3N a = 0470 nm and c = 0438 nm Peaks in XRD shifted through the annealing

however no line broadening was observed This depicts that concentration gradient of nitrogen atoms in

the particles did not occur and uniform distribution is realized

Mossbauer spectra recorded at room temperature are shown in Fig2 (A) The spectra for the as-nitrided

sample (a) compose of two singlets which indicates the sample was paramagnetic The sample (b) with

the H2 anneal for 2 h revealed to be in a magnetically order state where the magnetic transition temperature

is higher than room temperature The spectrum was fit to a distributed Hyperfine field( Hhf) spectrum and

the distribution histograms are shown in Fig 2(B) The peak in Hhf was observed at around 208 T which

coincides with that of ε-Fe26N[5] There are two extra peaks at lower magnitude of Hhf indicating the

distribution in magnetic transition temperature The spectrum for the sample (c) was composed of two

ferromagnetic sub-spectra The major component has a distributed Hhf with a peak Hhf of 238 T An

additional ferromagnetic component about 54 of area ratio was detected and the averaged hyperfine

field is 299 T It was also attributed to ε-Fe3N[5]

Diffusion process of the ε phase particles was analyzed using data for samples with different nitrogen

By the H2 annealing for 4 h nitrogen concentration decreased from 33 at to 25 at Taking ca = 33

at and c = 25 at the diffusion constant at 603 K was estimated to be D = 633times10minus20 [m2sec] This

is a diffusion constant of nitrogen in the hcp structure Dhcp

The diffusion constant of thin plate ε-Fe2minus3N was expressed as DεN = 168times 10minus7 exp(-118000RT)

m2sec[3] From the relation the bulk diffusion constant is found to be DεN = 101 times 10minus17 m2sec at 603

K It is about three order larger than that obtained in the present work The difference might be caused

by the anti-sintering process at the particle surface suppressing the nitrogen diffusion For reference the

diffusion constant of nitrogen in bcc α-Fe was expressed as D = 488 times 10minus7 exp (-76900RT) m2sec[6]

25

The value at 603 K is D = 106times 10minus13 m2sec This shows that the diffusion constant in hcp is essentially

smaller than that in the bcc phase

The diffusion constants of nitrogen atom in the hcp phase Fe both in bulk and small particles are

smaller than that in bcc phase The difference may originate from the characteristics of the crystalline

structure The hcp and fcc structures belong to the closed pack structure and movement of the guest atoms

among the interstitial sites has less probability than the case in the bcc (not closed packed) structure It

is interesting that the nitrogen diffusion constant is three order smaller than that in the bulk specimen

The smaller coefficient means that the nitrogen atoms do not move easily Providing the two dimensional

diffusion nitrogen penetration depth x is expressed as the relation x2 prop Dτ [7] From the relation the

uniform nitrogen concentration range in the fine particles was roughly speculated to be 10minus32 003

times smaller than that for the bulk Supposing 10 microm of the uniform range in bulk the nitrogen uniform

range for fine particles is estimated to be 300 nm This suggests the upper particle size of ε single phase

particles

41 Fluctuations in cosmic ray flux around 11 kyr BP based on cosmogenic 36Cl from the Dome Fuji ice core

K Sasa K Kurosumi Y Matsushi Y Tosaki T Takahashi K Sueki N Kinoshita K Horiuchi H Matsuzaki and H Motoyama

Cosmogenic radionuclides such as 10Be 14C and 36Cl are produced in the Earthrsquos atmosphere by the interaction of galactic cosmic rays with the atoms The connection between cosmogenic radionuclide production and the geomagnetic field is well understood [1] We reconstruct past changes in cosmic ray flux under the assumption that cosmogenic nuclide records are mainly influenced by changes in their production rates Cosmic ray fluctuations around 11 kyr BP have already been observed in 14C records from the analysis of 14C tree ring and 10Be data from the ice cores at Greenland [2] We report the results of 36Cl flux around 11 kyr BP from the ice core at the Dome Fuji station (77deg1901 S 39deg4212 E) in Antarctica [3]

Ice core samples were obtained from 370 m to 320 m below the surface of the ice sheet corresponding to ages of 123ndash105 kyr BP The record of 36Cl flux increases between 114 and 112 kry BP The result agrees well with 14C records derived from 14C tree ring and 10Be data measured from the Greenland ice cores Cosmic ray fluctuations derived from the 36Cl flux in the Dome Fuji ice core agree with independent geomagnetic field intensity reconstructions

Y Tosaki N Tase K Sasa T Takahashi and Y Nagashima

Introduction Understanding of groundwater flow system plays an important role in sustainable management of water resources Application of environmental tracers is one of the effective approaches for visualizing the movement of groundwater For the purpose of testing the potential of 36Cl to trace regional groundwater flow system with a time scale of ~50 years spatial distribution of 36Cl was investigated in the lower reach of the Yoro River basin Chiba Prefecture

Study area and methods The downstream area of the Yoro River is characterized by its surrounding Pleistocene uplands and alluvial lowlands along the river The climate in this region is humid temperate with an average annual precipitation of 15902 mm at Ushiku in the southern hilly area and 12938 mm at Chiba which is located on the northwestern side of the study area near the coast along Tokyo Bay A previous study clearly demonstrated the regional groundwater flow in the basin by using tritium as a tracer [1] Recharge mainly occurs at upland areas and the groundwater essentially flows into the lowland along the Yoro River eventually discharging into the river Groundwater samples were collected from 16 irrigation wells located within the basin (Fig 1) in July and August 2004 and analyzed for dissolved inorganic ions by ICP-AES and ion chromatography After standard chemical processing [2] 36ClCl ratios were measured with the AMS system at UTTAC

Results and discussion Table 1 lists dissolved anion concentrations and 36Cl data for the samples analyzed in this study Samples I-2 and I-10 showed relatively high Clminus concentration and high NO3

minus concentration as well possibly affected by anthropogenic chlorine source In order to minimize the possible mixing effect of artificial chloride 36Cl concentrations were used for data interpretation assuming a negligible content of 36Cl in chloride derived from such artificial source Figure 2 shows the distribution of 36Cl concentration projected onto the line A-B in Fig 1 Although sample I-1 is located rather far from the projection line it was also included as a value representing

groundwater in the discharge area Relatively low 36Cl concentrations were only found in the lowland near the river while the others showed higher values The observed distribution is basically consistent with the groundwater flow system traced by environmental tritium in 1980s [1] relatively young groundwater in the upland areas and old groundwater (gt30 years) in the lowland Low 36Cl concentrations in the lowland suggest even longer residence times probably more than 50 years Our observation demonstrates that the distribution of 36Cl is effective for tracing groundwater recharged during the last ~50 years

43 Measurement of 36Cl in soil Study of extraction methods according to reservoirs

T Amano K Sueki J Kitagawa K Sasa Y Nagashima Y Takaya T Takahashi N Kinoshita Y Tosaki Y Matsushi1 K Bessho2 H Matsumura2 Introduction Chlorine-36 which is a long life radioisotope is mainly produced by a nuclear spallation reaction with cosmic-ray on 40Ar in the upper atmosphere[1] The nuclide is distributed whole earth The atmosphere also contains 36Cl which is produced in atmospheric nuclear tests on the sea 36Cl in soil has important roles to search chlorine circulation We have measured 36Cl which was extracted with HNO3 from soil We examined sequential extraction methods for 36Cl determination

Experiments We examined extraction process of soil sample as shown in Figure 1 Soil sample which was dried and mashed up was extracted with 001 mol l HNO3 Precipitate of hydroxide was prepared by adding 3 mol l NH3 to extracted solution The precipitate was removed by a centrifugation and then AgCl was prepared (hereinafter ldquoArdquo) After extraction dried soil of 20 g was mixed with 70 ml of 002 mol l HNO3 and 70 ml of 30 H2O2 The extraction was carried out for 1 day and then solution was separated from the soil by a centrifugation AgCl from the solution was prepared (hereinafter ldquoBrdquo) after the same procedure described for ldquoArdquo After two times of extraction the soil was heated at 700 ordmC for 4 hours to remove organic matters and then heated at 1000 ordmC for 2 hours Generated gas was trapped in alkali solution which 85 g of NaOH and 085 g of Na2SO3 were dissolved in 170 ml of water 5 ml of 30 H2O2 was added to the alkali solution and then AgCl was prepared (hereinafter ldquoCrdquo) In addition the soil was heated at 1000 ordmC after extraction with 001 mol l HNO3 and AgCl was prepared (hereinafter ldquoDrdquo) Each AgCl sample was loaded to target cone for determination of 36ClCl isotopic ratio using an accelerator mass spectrometry at UTTAC[2]

Results and discussion Table 1 shows 36ClCl isotopic ratios and supply sources of Cl Cl isotopes extracted in sample ldquoArdquo is supplied from soil water because Cl extracted in sample ldquoArdquo is a soluble species in the diluted acid Cl in sample ldquoBrdquo and ldquoCrdquo are isolated from organochlorine compounds and inorganic minerals respectively Cl in sample ldquoDrdquo is mixture of ldquoBrdquo and ldquoCrdquo Not significant difference was found in 36ClCl isotopic ratios between ldquoArdquo and ldquoBrdquo 36ClCl isotopic ratio in sample ldquoCrdquo is higher than ldquoArdquo and ldquoBrdquo 36ClCl isotopic ratio in organic matter and soil water show similar ratio However 36ClCl isotopic ratio in inorganic minerals shows higher 36ClCl isotopic ratio ______________________________________________________________________

of 675 m Then the muons were passed through an iron beam dump and rock Fig 1 shows the beam line of NuMI There are 4 rooms at depths of 0 m 137 m 335 m and 671 m from rock surface The rooms are named Alcove-1 Alcove-2 Alcove-3 and Alcove-4 respectively The samples of sodium chloride and calcium carbonate were installed in each room for the irradiation The irradiation was carried out for 3 month Chlorine-36 in the irradiated samples were analyzed by an Accelerator Mass Spectrometry (AMS) at University of Tsukuba The samples of sodium chloride and calcium carbonate were dissolved in water and nitric acid respectively Carrier of natural chloride ion was added to the calcium carbonate sample The chloride ion was precipitated as silver chloride Subsequently reduction of sulfur ion was carried out using barium nitrate solution The purified samples were subjected to the AMS measurement

The chlorine-36 could be produced from 35Cl and 37Cl for sample of sodium chloride calcium isotopes for calcium carbonate Production rates of 36Cl in each sample were calculated using number 36Cl atom produced in the sample and number of target Totally 756times1019 of protons have been bombarded to the graphite target Fig 2 shows production rate of 36Cl The production rates at Alcove-1 (0 m) are observed to be higher than the trend expected from Alcove-2 3 and 4 Each data except for Alcove-1 could be fitted using an exponential function with slopes (mminus1) of (minus655 plusmn

066) times 10minus2 for sodium chloride and (minus622 plusmn 015) times 10minus2 for calcium carbonate Attenuation length (gcm2) could be calculated from a rock density and the slope The attenuation lengths were calculated to be 4100 (gcm2) for sodium chloride and 4300 (gcm2) for calcium carbonate using 265 (gcm3) for the rock density The lengths of present work correspond well with reported values of 5300 by Braucher et al [2] and 4360 by Heisinger et al [3] Information on muon flux and energy spectrum using Monte Carlo code of Geant4 and MARS etc are required for more detailed discussion as a future plan

36Cl is one of the cosmogenic radionuclides found in meteorites and produced by several nuclear reactions such as proton and neutron induced spallation reactions and neutron capture reaction Cross sections of those reactions depend on particle energies characteristically Thus it is suggested that additional information must be obtained from 36Cl production rates normalized by a weight of target element (in dpmkg) for individual target element So we have been trying to determine production rates

of 36Cl especially one from 35Cl(n γ) reaction [1 2] Last year 36Cl contents and chemical compositions were determined in several different mineral phases separated from two chondritic meteorites fragments Gold Basin and Gao[2] This year Cl concentrations in separated phases were determined by radiochemical photon activation analysis (RPAA) and production rates of 36Cl were calculated And 36Cl contents were determined in additional Gold Basin fragments

Chemical composition of several silicate phases separated from two fragments of Gold Basin and one fragment of Gao were already determined by instrumental neutron activation analysis (INAA) last year Their Cl concentrations were determined by radiochemical photon activation analysis (RPAA) And 36Cl contents in new fragments of Gold Basin were determined by same manner in [2] Chemical compositions of new fragment were not still determined

Production rates were calculated from combination of Cl concentration by RPAA the other target elemental concentration by INAA and 36Cl contents in several phases Since the number of phases with different chemical compositions was insufficient to calculate production rates for whole target elements (Co Ni Fe Mn Cr V Ti Sc Ca and K) production rates for several target element groups (Ca+K) (Fe+Ni) and Cl were calculated In this case contribution of 36Cl production from the other target elements was ruled out because of their trace elemental concentration

Production rates of 36Cl calculated by least square method (LSQM) and alternative least square method (ALSQM) are listed in Table 1 Chlorine concentration in both metal phase and acid - dissolved phase were not determined by RPAA For LSQM Cl concentration in metal phase was

assumed to be 0 and one in acid - dissolved phase was estimated from ones in silicate phase and acidndashinsoluble phase ALSQM can calculate production rates under that Cl concentration values in these two phases were defective values Production rate of 36Cl for the

reaction induced by neutrons (35Cl(n γ) and 37Cl(n 2n)) were obtained only experimentally for the first time Since 35Cl(n γ) reaction cross section of thermal neutron is very higher than spallation reaction by proton production rate for Cl is extremely larger than ones for (K + Ca) and (Fe + Ni) Difference between calculated production rates for (K + Ca) elements by LSQM and ALSQM was significant This difference is supposed to be caused that Ca and K concentrations in phases obtained in this work were smaller compared to Fe and Ni concentrations We have to prepare a phase that K and Ca are major composition to obtain more accurate production rate for (K + Ca)

Welten et al[3] determined 36Cl and 10Be contents in 15 fragments of Gold Basin and estimated contribution of spallation reaction and neutron capture reaction for 36Cl production in conjunction with a model calculation In Fig1 their estimation and our result for silicate phases are compared Our values are consistent with estimation by Welten et al thus production rates obtained in this work are concluded to be reasonable values

36Cl contents in metal phases of new fragments of Gold Basin were different from ones in fragments 1 and 2 This suggests that 4 fragments were originated with different depths in the meteoroid Using new fragments additional production rates will be calculated and depth profile of production rate will be evident

51 Trace-element analysis of fluid inclusions in the Tsushima granite Japan

M Kurosawa S Ishii and K Sasa

Introduction Fluid released from granitic magma during solidification plays a key role in formation of various metal-ore deposits hydrothermal alteration and chemistries of deep groundwater around granite bodies A part of the fluid is normally trapped as fluid inclusions in the solidified granite and surrounding rocks Thus the fluid inclusions provide useful information about chemistries and behaviors of the fluid The Miocene granite pluton in Tsushima Islands accompanies the largest Pb-Zn metal-ore deposits in southwestern Japan and is well known for its abundant hypersaline fluid-inclusions in quartz crystals [1] Chemical analyses of the fluid inclusions therefore are expected as an information source about genesis of the granite-derived fluids and its large-scale metal transport in the island arc For these reasons we analyzed trace metal-elements in the fluid inclusions at the Tsushima granite by using micro-PIXE

Sample The Tsushima granite Nagasaki prefecture Japan is mainly composed of biotite granites and contains abundant miarolitic cavities and rarely quartz veins The estimated emplacement level is 2-6 km deep [2] Quartz in the granite and the miarolitic cavities includes so many polyphase fluid inclusions with large daughter crystals of halite calcite and hematite (Fig 1) In this study we focused fluid inclusions in the miarolitic cavities to investigate an original composition of fluids released during

solidification of the granite Salinities of polyphase inclusions in the cavities were of 28-48 wt NaCl eq and the homogenizing

temperatures (Th) ranged from 480 to 200 degC Vapor- and liquid-rich two-phase inclusions were also included Two-phase

inclusions of the cavities showed almost Th of 400-200 degC Measured inclusions were an ellipsoidal or negative-crystal

shape and the inclusion depths were less than 10 microm

Experimental The PIXE analyses were performed at the 1MV Tandetron A 10 to 50 nA beam of 192-MeV proton was

focused to a 100 x 100 microm spot on the sample The beam incidence was normal to the sample surface and the X-ray measurement take-off angle was 45 (Fig 2) The characteristic X-rays excited by the incident beam were collected by the Si(Li) X-ray-energy detector with a nominal resolution of 153 eV at 59 keV A

55-microm-thick Mylar film was used to attenuate the intense X-rays from the predominant light elements

The total charge was determined by integrating the target currents and all samples were analyzed to the

integrated charges of 05 to 50 microC Analytical points were chosen based on optical viewing using a CCD camera mounted on the microscope [4] Quantification was performed based on the model of Kurosawa et al [3 4] By using the model almost trace elements in fluid inclusions at levels of a few ppm to wt can be

determined with the total analytical error of plusmn11- 40 [4]

Results and Discussion PIXE spectrum of a polyphase inclusion in the cavities is shown in Fig 3 Most of the inclusions demonstrated the similar X-ray spectra Element concentrations of the polyphase inclusions were as follows ~25 wt for Cl 7 wt for Fe 1-5 wt for K Ca and Mn 7000 ppm for Ba 1000-3000 ppm for Zn Pb Cu and Br 100-300 ppm for Rb and Sr The compositions are thought to correspond to the original contents of hydrothermal fluid released from the Tsushima granite during solidification The determined values are several times higher than the values of polyphase inclusions in miarolitic quartz from the Miocene Kofu granite Japan that has emplacement level 5-8 km deep [5] The Tsushima granite solidified at extensively shallower level (2-6 km deep) so that a hypersaline fluid were easily formed by decompression boiling during generation of the hydrothermal fluids The high contents of transition-metal elements in the polyphase inclusions were also attributable to the element partitioning at the boiling Thus a shallow emplacement level of granite body is important to formation of granite-derived fluids with high salinity and high metal content

52 Nanopore fabrication by irradiating accelerated ions for high- sensitivity waveguide-mode sensors

M Fujimaki1

and K Awazu1

Highly-sensitive molecular detection sensors are required in various fields of application We have developed an evanescent-field-coupled waveguide-mode (EFC-WM) sensor [1] Figure 1 is a schematic showing the setup of the sensor The sensing plate illuminated under the Kretschmann configuration operates as a sensor that is capable of detecting modifications in the dielectric environment near the waveguide surface with superior sensitivity by measuring change in reflectivity [1] Sensitivity of an EFC-WM sensor strongly depends on the optical constants of its reflecting layer By theoretical calculation and experiments we found that Si is an ideal material for the reflecting layer [2] Based on this finding we developed a monolithic sensing plate consisting of a SiO2 glass substrate and a thin single crystalline Si layer the surface of which is thermally oxidized to form a SiO2 glass waveguide [3]

Fig1 Schematic of the setup of the EFC-WM sensor using the Kretschmann configuration We has reported that a significant enhancement of sensitivity of EFC-WM sensors was achieved

by perforating the waveguide in which selective etching of latent tracks formed in the waveguide by swift heavy ion irradiation was used The monolithic sensing plate is suitable for the nano perforation process [3] In the present research we examined the correlation between the sensitivity of the sensor and the sizes and densities of nano holes formed in the waveguide of the monolithic sensing plate The waveguide was perforated by sequential swift-heavy-ion irradiation and etching with hydrofluoric acid (HF) vapor Ion irradiation was performed by using the 12 UD Pelletron tandem accelerator at the University of Tsukuba and the waveguide was irradiated with Au ions at room temperature in a vacuum of about

5times10minus4 Pa The average acceleration energy was 137 MeV For the vapor etching the irradiated plate and a 20 aqueous solution of HF were placed in a container so that the plate was not immersed in the solution but was suspended close to its surface The resulting nano holes were observed by scanning electron microscopy (SEM Hitachi High-Technologies S4800)
