The Application of the X-Ray Laws to Optical Spectra of Higher Rank, and the Classification of Ga IV and Ge V

Abstract

Spectra of Ga IV and Ge V.—By application of the Moseley law and the two doublet laws of x-ray spectroscopy, the ($3d^{9}4s$) and ($3d^{9}4p$) levels of Ga IV and Ge V and a tentative ($3d^{10}$) level for Ga IV, have been found. The levels formerly classified as ${}_{}{}^3{}_{}{}^{}D_1^{}{}_{}{}^{}$, ${}_{}{}^1{}_{}{}^{}P_1^{}{}_{}{}^{}\left(3\mathrm{}{d}^{9}4p\right)$ of Zn III have been interchanged.
