The Absolute Absorption Coefficient of Germanium and the Fine Structure in theKEdge of Some of its Compounds

The fine structure of the $K$ absorption limit of Ge in Ge${\mathrm{H}}_4$, ${\mathrm{Ge}}_2$ ${\mathrm{H}}_6$, Ge${\mathrm{Cl}}_4$, and Ge${\mathrm{Br}}_4$ has been obtained with absolute values under conditions of high resolution with a double crystal x-ray spectrometer. Results are compared with existent theory and previous measurements and discrepancies are pointed out. The question of the location of an absorption edge is considered along with the Kossel structure appearing in the germanium hydrides.
