Abstract
The codes used to calculate stopping power and range for the space radiation
shielding program at the Langley Research Center are based on the work of Zieglerbut with modifications. As more experience is gained from experiments at heavy ion
accelerators, prudence dictates a reevaluation of the current databases. Numerical
values of stopping power and range calculated from four different codes currently in
use are presented for selected ions and materials in the energy domain suitable for
space radiation transport. This study of radiation transport has found that for mostcollision systems and for intermediate particle energies, agreement is less than I per-
cent, in general, among all the codes. However, greater discrepancies are seen for
heavy systems, especially at low particle energies.
1. Introduction
Both analytical and experimental approaches are
needed when studying the transport of space radiation for
the purpose of protecting astronauts and flight instru-
ments. Experimental work is important because it serves
as the ultimate verification, but it is expensive and time-
consuming. Analytical (or computational) approaches,
therefore, are needed as a tool to obtain the necessary
information. One essentially tries to solve the Boltzmann
transport equations (ref. 1) with proper boundary condi-
tions and data input files, such as stopping power, ranges,
nuclear fragmentation cross sections, nuclear absorptioncross section. Accurate and reliable information about
stopping powers and ranges is therefore important in the
study of radiation transport. The purpose of this report is
not to give an in-depth description of the physical mech-anism nor the various computational models but rather to
compare the numerical results generated by some of the
codes currently in use and to establish how the resultscalculated with different codes differ from each other.
The present code (referred to as the "LaRC code") is
based on the work of Ziegler (refs. 2 to 7) with the heavy
ion Thomas-Fermi scaling rule being used. However,
modifications to Ziegler's basic method were made.
Ziegler (Ziegler code) based his algorithm on a fit to
experimental data, and for the present study we use it in
the same domain. For extrapolations to other domains ofinterest, we made some exceptions to Ziegler's method.
Bichsel (RSTAN and RSHEV codes) states that his
parameters are based on more recent experimental data.The third and fourth sets of limited data are from the
work of Hubert (Hubert code) (ref. 8) and Janni (Janni
code) (ref. 9). The values of stopping power and range
generated by these codes are presented for different pairs
of particles and absorbers in different energy domains. Insections 2, 3, and 4, the basic definition and nomencla-
ture of stopping power and range theory are discussed,
and in section 5, the LaRC code is briefly described. Insection 6, the numerical comparisons generated by dif-
ferent codes are briefly discussed.
2. General Theoretical Considerations
A fast charged particle traversing matter makes colli-
sions and loses energy to atomic electrons and nuclei. An
important difference in the loss mechanism is present if
the medium is in a gas phase or in a condensed phase. In
isolated atoms, the smallest energy losses are to discreteexcited electronic states, and ionization occurs for energy
transfer exceeding the binding energy of each atomicshell (ref. 10). When atoms are brought closer together to
form a liquid or solid, their valence electrons are under
the influence of the cores of surrounding atoms. A coreconsists of the nucleus and all the electrons inside the
valence shell. For metals, the valence electrons form a
conduction band where the electrons are nearly free. If a
charged particle moves through the solid, the transfer ofvery small energies to the electrons by Rutherford scat-
tering is not observed. Instead many thousands of
valence electrons interact simultaneously with the parti-
cle, and this interaction leads to many bodies in excited
states. For metals, this process is called a plasmon excita-tion; for insulators, a collective excitation.
For particles heavier than electrons, the collisionswith absorber electrons and nuclei have different conse-
quences. The electrons can receive large amounts of
energy from the incident particle without causing signifi-cant deflections, whereas the nuclei absorb very little
energy but cause scattering of the incident particle
because of their greater mass. The deflection of the parti-cle from its incident direction results mainly from elastic
collisions with the nuclei. The scattering is confined to
rather small angles; therefore, a heavy particle keeps a
more or less straight path until it nears the end of its
range.
The study of stopping power and range theory has
attracted physicists for the nine decades since the days
Madame Curie discovered radioactivity in materials.
Hundreds of papers and dozens of review articles have
been written on this vast subject. (See, e.g., refs. 10 to
22.) The stopping power is defined as the mean energy
lossperunit pathlength-dE/dx. Therangeof aparticleof giveninitial kineticenergyE 0 is defined as the mean
path length traveled before coming to rest. In the contin-
uous slowing-down approximation, the range R(Eo) can
be expressed as the integral over the reciprocal of stop-
ping power from zero energy to E0.
correction terms (refs. 24, 25, and 26), the final equationcan be written as
41_Z_Z2 e4 f C(_) +s- ZTv Nl 0-%-
For speeds v greater than c/137, the basic loss mech-
anism is well understood, especially for light ions such as
protons and alpha particles. The analytical predictions
and experimental results agree within 3 percent. How-
ever, when the ion and/or the target are heavy or the inci-dent energy is low, the calculations and experimental
results begin to show larger discrepancies. At lower par-
ticle energies (i.e., at v < c/137), which are comparable
with those of outer atomic electrons, capture and loss of
electrons by the penetrating particle complicate its
energy loss processes.
3. Basic Formula of Energy Loss
A particle of mass M l and charge Zle penetrates a
material composed of atoms of atomic number Z 2 andatomic mass M 2. The projectile interacts via the electro-
magnetic force with the electrons and nuclei of the
medium and via the strong nuclear force with the nucleiof the absorber. For thin absorbers, the nuclear force can
be disregarded to first order because the ratio of the
nuclear to atomic cross sections is very small (=10-8).
The projectile slows down mainly by losing energy to theelectrons of the absorbing medium. Different approaches
to this energy loss lead to similar expressions. The com-
monly accepted model is the Bethe solution, and most
recently developed approaches follow closely the Betheapproach by fine-tuning some of the parameters in themodel.

where

is the asymptotic stopping number, e is the electronic
charge, N is the density of the atoms in the target,
ra is mass of electron, c is speed of light, 13 = v/c, and72= 1/(1 - _2). Equation (1) serves as the common foun-
dation of most theoretical treatments of stopping power.
The various parameters in equation (1) are consid-
ered next. The mean excitation energy I is treated as a
property of each material defined by
where
In(1) = Z fn ln(En) (3)n
2/. = h2z---(4)
is the dipole oscillator strength for the nth energy level
and h = h/2n (where h is the Planck constant). Equa-tion (4) satisfies the Thomas-Reiche-Kuhn sum rule
Bethe's treatment (ref. 23) of the energy loss is
based on the Born approximation applied to the colli-sions between the heavy particle and the atomic elec-
lyons. In this theory, the projectile heavy particle is
assumed to be structureless, and the target nucleus isassumed infinitely massive. The differential cross section
for a process in which the heavy particle transfers a given
momentum to the atomic electrons is given by the squareof the matrix element of the Coulomb interaction
between appropriate initial and final states. Plane wavesare used for the wave functions of the incident and scat-
tered heavy particle. The initial state of the atom for the
ground state is described by the unperturbed atomic wave
function; for the final state, by the wave function for one
of the excited states. Multiplying the cross section for
a given energy loss by the energy loss and summing
over all possibilities give the final expression for the
average energy lost per atom. With relativistic and other
Z fn = 1 (5)n
However, Rustgi, Leung, and Long have shown thatfor the heavy systems, a sum-rule calculation in a semi-
relativistic approach may lead to inaccurate results
(refs. 27 and 28). The determination of/presents consid-
erable difficulty because the most important excitationenergies E n lie in the range of 10 to 1000 eV where the
oscillator strengths fn are poorly known. Usually, thevalue of I is treated as an adjustable parameter deter-
mined empirically. For rough estimates of I, the approxi-mation (ref. 29)

is useful,togetherwith theBraggrulefor compoundsandcompositematerials
n e ln(1) = _ n i ln(li) (7)i
where n i is the electron density associated with element i
and n e is the average electron density.
In equation (1), the correction terms are as follows:
Shell correction: The asymptotic expression for the
stopping power depends on the assumption that
the speed of the incident heavy particle is much
higher than that of the atomic electrons in their
normal bound states. This approximation is inade-
quate, especially for the inner shell electrons of
the heavy elements that move with much faster
speeds. The correction C([_)/Z 2 is defined as an aver-
age over the contributions of the several shells, with
C = C K + CL + .... Each shell correction can be esti-
mated by using hydrogenic wave functions (refs. 16,26, 30, 31, and 32).
Barkas term: The term LI(I] ) arises from polariza-
tion of the target electrons by the incident particle.
The Barkas effect is the difference in stopping power
of heavy particles of opposite charge under other-
wise equal conditions. Positively charged projectiles
draw atomic electrons closer to them, whereas nega-
tively charged projectiles repel electrons. The obser-
vation of the Barkas effect signaled the start of a gen-
eral study of the departure of energy loss phenomena
from the scaling law of the plane-wave Born approx-imation. These differences are alternatively called
Z31 effects because the theoretical accounts that have
been developed to address this phenomenon treat
terms to this order. Since the Z_ term appears to
arise from distortions of the target electron motion or
wave function during the collision, it is also referred
to as a "polarization effect" So far, the status of
experiment and theory does not provide a definite
conclusion. The role of high-order terms in inner-
shell ionization as the primary origin of the Barkaseffect has been suggested. (See refs. 33 and 34.)
Bloeh term: The term L2(_) arises from correctionsto the approximation that for close collisions, the
outgoing electrons can be represented by planewaves (refs. 33, 34, and 35). Bloch considered an
intermediate impact parameter bl, and assumed thatthe electrons confined to the interior of a cylinder of
radius b I cannot be represented by plane waves. Thisassumption introduces transverse momentum com-
ponents that interfere with one another under the
influence of the scattering potential; this results inthe Bloch correction term
2£ 1Z_L2([3 ) = -y
j=l j(j2 + y2)
(8)
where y = ZlOt./[_ and the fine structure constant ot
equals 1/137.04.
Mott term: The term G(M¿,_) is a kinematic recoil
correction, which becomes important for relativistic
projectiles. For a spinless nucleus, the correction is
(ref. 21)
G(MI,[_ ) = In(1 +2t)---t[_2
27
(9)
where t = mTIM 1.
Density correction: The term _5(13)arises from the
dielectric response of a solid absorber as a whole to
the electric field generated by the projectile and the
work done by the interaction. Sternheimer (ref. 36)
and Sternheimer and Peierls (ref. 37) have given the
expressions as well as the parameters to be used in
an approximation for the density effect correction.
Shinn et al. (ref. 38) have taken the asymptotic
expression suggested by Sternheimer as a correctionin the LaRC code.
Other corrections: The corrections in equation (2)
may not be independent. For example, Basbas
(ref. 33) has suggested that to separate Bo from L1
and L2 may not be plausible. In addition to the cor-
rections mentioned previously, other important cor-rections at ultrarelativistic velocities include (1) radi-
ative correction, (2) projectile structure correction
(represented by the nuclear form factor), and
(3) bremsstrahlung and pair production.
At small projectile energies, the various correction
terms in equation (2) become large compared with B0. Inparticular, for 2my 2 = 1, Bo becomes zero. For example,
as pointed out by Bichsel (ref. 26) for ct particles
impinging on uranium (I = 840 eV), B o equals 0 at
E0 = 1.5 MeV, and S consists only of correction terms.
For smaller energies, an empirical approach is used to
describe S. Heavy ions at small energies have electrons
attached and thus have a reduced charge Z l < Z 1. If Z lis defined to give the correct observed stopping power, it
is not equal to the mean charge per particle of a beam
leaving an absorber. An equation commonly used for the
3
effectivechargehasbeenpublishedin references39and40andis
Z1 = 1 - exp(-1.316x + 0.1112x 2 - 0.0650x 3)Z 1
(10)
where x = IO0_IZ_/3.
In the LaRC code, the following formula proposedby Barkas (ref. 41) has been used:
z;-- = 1 - exp(-1.25x)Z l
(11)
The difference in Z_ in equations (10) and (11) is no
more than 2 percent for all speeds and Z 2. Hubert,Bimbot, and Gauvin published another effective charge
pararneterization formula (ref. 8), which depends on both
Z 1 and target charge number Z 2.
4. Range-Energy Relations
The mean path length in the continuous slowing-
down approximation (CSDA) is defined as
_EE° S -1R(Eo) = dE (12)
where Emi n is the thermal energy of the particle. For
practical purpose, Emi n can be set to zero.
5. Description of LaRC code
An outline of the procedures used in the LaRC code
is given in this section with energy E in kiloelectronvolts.
5.1. Electronic Stopping Power for Protons
In the LaRC code, which follows the approach of
Ziegler, the section that evaluates the stopping power ofprotons is generated in subroutine ATOPP. The modified
Ziegler results are used as follows:
Sp =
)
al,fE (0<E_< 10 keY) /

SLSH ( 10 keY < E < 999 keV)(SL + SH) - _

(13)
where
S L = a2 E0"45 (14)
a'Ia4 1S H = -_ In l+-_+a5E (15)
, { c,o'177)C = X a7+i [ln(E)]i-1 1-exp 2 Ti=1
(16)
where Ziegler's parameter a i is used and 5 equals the
density effect obtained from the Sternheimer asymptotic
form. In equations (13), in the high-energy expression,the density effect and the post factor in equation (16) (the
term in braces, that is, {1-exp[-2(105/E)2]}) have
been added to the Ziegler expression. This post factor
was chosen so that shell correction vanishes for large E.
(See section 4 in ref. 17.) The coefficients al,a 2..... a12can be found in tables 1 and 2 in reference 13.
5.2. Electronic Stopping Power for a Particles
In the LaRC code, the section that evaluates the stop-ping power of a particles is generated in subroutine
ATOPA with the following algorithms:
So_ ---
• a 2
ale (E < 1 keV)"
SLSH(1 keV <E< 104 keV)
(S L + Sn)
S I (10 4 keV <E < 2 x 104 keV)

(17)
where
S L = al Ea2 (18)
f '0304SH = E In 1 + -----_-- + a 5 (19)
$1= exp{a6+a 7 lnI'm_----)+a8[ln(l_0)l 2
(20)
Thecoefficientsal,a 2 ..... a9 for the t_ particle are
from reference 5. Ziegler's coefficients are for the phase
of material where experiments were performed exceptfor hydrogen where values for the condensed phase are
used. The term Sp is simply the proton stopping power atthe corresponding speed.
5.3. Electronic Stopping Power for Other Ions
The scaling scheme from the stopping power of the
particle was adopted to obtain the ion stopping power
in subroutine SIONA by
, 2(Zion)
Sion - , 2 S_ (21)(z_)
where S a is the stopping power of _ particles and Z isthe effective charge defined in equation (11).
5.4. Nuclear Stopping Power
In the LaRC code, the section that evaluates the
stopping power of incident ion due to the screened
Coulombic potential of the target nucleus is generated
as ATOPN. The treatment of Ziegler is followed in
expressing the universal nuclear stopping power in terms
of reduced energy and universal screen length. (See
ref. 2.)
6. Numerical Results
Proton stopping power results generated by the
LaRC code and the results published in reference 4 (from
the multivolume work edited by Ziegler) are presented
for nine targets at a low energy of 0.01 MeV to a medium
energy of 100 MeV, where Ziegler's table ends. Al-
though some modifications to Ziegler's parameters were
made, such as density effect and cutoff factor, the numer-
ical differences in these energy ranges are small; thus, anumerical comparison is not presented. However, the dif-
ferences are expected to increase as ultrarelativistic ener-
gies are approached. Ziegler's results would have a
logarithmic divergence behavior which is not physical,
whereas the present results clearly have been properly
corrected by the cutoff factor in equation (16). Next the
contribution of the density effect correction to the total
stopping power was explored. The formalism of
Sternheimer (ref. 36) as implemented by Shinn et al.
(ref. 38) was adopted; however, only the asymptotic
expression, which is much easier to implement, was
used. Armstrong and Alsmiller (ref. 42) have shown
overestimation by using the asymptotic formula because
the value of the density effect is no more than 6 percent.
Slight inaccuracies in a small correction are assumed tohave negligible influence and can be tolerated. The data
in table 1 clearly show when the density effect eontrib-
utes appreciably as a function of impinging energy. At
extremely high energies, for example, beyond 500 GeV,
the data in table 1 suggest that density effect could make
more than a 20-percent contribution to the total stopping
power.
In table 2, the present results and the stopping power
values of Janni are given. He used a different scheme forthe corrections. For the shell correction, he obtained a
total correction by calculating the correction of each sub-
shell and then summing the results. For the density
effect, the correction was calculated from first principles
for each material from the fundamental equations; the
material independent term was not included. The
adjusted ionization potentials were determined in a
weighted least-squares analysis by fitting the Bethe equa-
tion to the experimental data. In the low-energy region, a
different fit of experimental data was used including
nuclear stopping. In table 2, when comparing the data
from the LaRC and Janni codes, good agreement is found
with the proton energy above 40 keV except when iron isthe target. Then a consistent discrepancy of 5 to 10 per-
cent throughout the whole energy range is seen. Also, the
difference between the two results can go as high as
30 percent at the low-energy end (10 keV).
In tables 3, 4, and 5, the results from the LaRC and
the Hubert codes are presented. The tables of Hubert,
Bimbot, and Gauvin (ref. 8), whose scheme includes a
more elaborate effective charge parameterization for-
mula that includes a dependence on Z 2 (the target atomic
number), are used. Hubert claims that the dependence is
necessary in order to be able to reproduce the whole set
of experimental stopping powers. From tables 3, 4, and 5,
for the limited systems and the energy specified, whichlacks low energies, however, the two results seem to
agree very well.
The results of the LaRC and Bichsel codes are pre-sented in tables 6 to 11. Because Bichsel states that his
code is only reliable for EIA > 2.5 MeV/nucleon and for
Z 1 < 20, the low-energy data are questionable; these datashould be disregarded in tables 6 to 11. For the space
radiation transport studies, p, e_, C, Ca, Ar, and Fe were
used as the projectile ions; C, Cu, Au, U, and H20, as the
targets. The energy range is from =2 MeV to =50 GeV,
depending upon the collision partners. In fact, two
slightly different versions of the Bichsel code were used:RSTAN and RSHEV. In the RSTAN code, Bichsel uses
the K- and L-shell corrections originally derived by
Walske with the nonrelativistic hydrogen approximation
(refs. 31 and 32), and he further uses the scaling proce-dure on the L-shell for the outer shells, whereas in
RSHEV he uses the separate subshell corrections for
three L-subshells, five M-subshells, and the scaling pro-
cedure for the outer shells (N, O, and P). The RSHEV
5
code is supposedly more suitable for heavier targets
because of more detailed shell correction treatment.
Which code was used is clearly stated in tables 6 to 11.
The RSHEV code was used for targets Au and U and all
projectiles except Fe, and the RSTAN code was used for
Fe projectiles and targets Au and U simply because it
generated better agreement. The reason for this better
agreement is not clear. Tables 6 to 11 are arranged
according to weight of the projectile and the target; the
last target, water, is a compound. Table 6 gives stopping
powers which show good agreement, especially for
lighter targets. The range values show greater difference
because of the larger difference in stopping values in the
low-energy domain, which contributes to the range val-
ues through integration. In tables 6 to 1 1, as the projectile
gets heavier, in general, the agreement gets worse with
the Fe-U system being the worst (table 11 (e)). At a total
energy of 145.60 MeV (2.6 MeV/nucleon), the differ-
ence can be as high as 35 percent in stopping power and
43 percent in range values. Of course, the discrepancy is
expected as the colliding system gets heavier; this
implies that the physics involved becomes more compli-
cated. However, judging from tables 5, 1 l(d), and 1 l(e),
for iron as the projectile, the results indicate that the
LaRC code agrees better with the Hubert code than with
the Bichsel RSTAN code. Sometimes, the range values
calculated at low energy by Bichsel show negative
results (e.g., in table 10(c)) which of course are the result
of an interpolation error.
7. Concluding Remarks
With four different codes, a numerical comparison
of stopping power for selected collision pairs of materials
covering a wide range of energies was performed. The
purpose of this study was to survey the currently avail-
able stopping power and range prediction codes and to
reassess the present databases in the Langley transport
code. For the lighter projectiles, such as protons and
alpha particles, in a wide energy domain, the agreement
is fairly good for light targets. The discrepancy is less
than 3 percent for stopping power values but is a little
worse for range values. As the target becomes heavier, in
general the discrepancy gets worse, especially for low
energies. Based on this numerical exercise, the stopping
power and range databases used in the Langley transport
code are still acceptable for most impact energies and in
most of the collision systems. For the extremely low
energies and extremely heavy systems, further experi-
mental data are needed for the databases.

13. ABSTRACT (Maximum 200 words)
The codes used to calculate stopping power and range for the space radiation shielding program at the LangleyResearch Center are based on the work of Ziegler but with modifications. As more experience is gained from exper-iments at heavy ion accelerators, prudence dictates a reevaluation of the current databases. Numerical values of
stopping power and range calculated from four different codes currently in use are presented for selected ions andmaterials in the energy domain suitable for space radiation transport. This study of radiation transport has foundthat for most collision systems and for intermediate particle energies, agreement is less than 1 percent, in general,among all the codes. However, greater discrepancies are seen for heavy systems, especially at low particle energies.
