L23-M/sub 4,5/M/sub 4,5/ principal and satellite Auger spectra of Cu, Zn, and Ga

The L23-M/sub 4,5/M/sub 4,5/ principal and satellite Auger spectra are synthesized for atomic Cu and compared to the measurements in solid Cu. It is found that the L2-L3M/sub 4,5/ Coster-Kronig rate is significantly different in intermediate coupling from its value in j-j coupling. With intermediate coupling and matrix elements obtained with a Cu-ion potential (with an L-shell hole), the synthesized satellite spectra do not agree with the Cu measurements, but do agree with the measurements on Zn, when the energy scale is suitably contracted. With L2-L3M/sub 4,5/ matrix elements obtained with a neutral-atom Cu potential, the synthesized Cu spectra are in quantitative agreement with the measurements. However, in this case the calculated Cu L2 linewidth is significantly larger than the measured values. All the required transition-rate expressions in intermediate coupling are presented
