KX-Ray Absorption Spectra of Some Compounds of Bromine and Rubidium

Abstract

The $K$ x-ray absorption spectrum of Br in KBr, RbBr, Cd${\mathrm{Br}}_2$, and NaBr${\mathrm{O}}_3$ and of Rb in RbBr is obtained by using powder absorbing screens with a double crystal ionization spectrometer. Methyl iodide is used in the ionization chamber to eliminate the effect of Br in methyl bromide. The width of the Br edge is about 9 volts and of the Rb edge about 11 volts. The positions of secondary fine structure discontinuities are given and discussed. No discontinuity due to a possible simultaneous ejection of $K$ and $L$ electrons is observed.
