New type of auger effect and its influence on the x-ray spectrum

It is pointed out that the radiationless transition L_I → L_III with simultaneous ejection of an outer electron is of great importance in the interpretation of several features in the X-ray spectra, hitherto unexplained. It is responsible for the abnormal weakening of the emission lines with L_I as initial level (§ 1); the large intensity of the L_III-satellite lines within certain ranges of atomic number both for cathode ray and fluorescent excitation (§ 2) ; the greater diffuseness of the L_I-emission lines as compared with the L_II, L_III-emission lines (§ 3). It seems reasonable to assume that in the M-region similar radiationless transitions occur with analogous results.
