X-Ray Absorption Structure of GeCl4and AsCl3

Abstract

The fine structure on the short wave-length side of the $K$ x-ray absorption edges of Ge and As in Ge${\mathrm{Cl}}_4$ and As${\mathrm{Cl}}_3$ has been measured with a double crystal spectrometer having resolution sufficient to resolve all structure predicted by theory. The results are compared with the theory and with previous measurements made with spectrographs of lower resolving power. Structure is obtained closer to the edge than that resolved heretofore, which structure is not altogether in agreement with the theory.
