X-Ray Spectrography--Two Theta Values for EDDT John E. Fagel, Jr., Robert B. Madden, Harold Pikler and Harry T. Stephenson*

Refractory Metals Laboratory, Lamp Wire and Phosphors Department

General Electric Company, Cleveland, Ohio

Abstract Two theta values for EDDT have been calculated and tabulated

for wavelengths between 0 701 A and 8.735 A m the first through fourth orders.

The advent of the gas flow proportional counter tube and the flat reflecting crystal EDDT has made practicable the extension of X-ray spectrography to most of the third period elements. It is expected, therefore, that the EDDT crystal will enjoy increasing use, although it will not have the general applicabdlty of crystals such as sodmm chloride and lithium fluoride.

Normally EDDT wall be used only in the detection of low atomic number elements. The need for a detaded table of two theta values for this crystal would be slight, therefore, were it not for the following:

1, Second and higher order reflections of short wave- length X-rays (heavy elements) appear in the same angular regmn as the first order long wavelength X-rays characteristic of the lighter elements.

2. I t is inconvenient to change the counter tube and

ing the EDDT spectra of miscellaneous routine samples, and samples which contain both low and high atomic num- ber elements.

The Bragg equation was used to calculate the two theta values. The wavelength data and the EDDT crystal spacing d ~ 4.404 A) were taken from the hterature ( I , 2) .
