RELATIVE INTENSITIES OF L2,3M4,5M4,5 PRINCIPAL AND SATELLITE AUGER-SPECTRA OF CU

The L2,3M4,5M4,5 and L2,3M- MM4,5M4,5 Auger spectra of Cu have been measured using CuL, MgK, and AlK X-ray exciting radiation. L2M4,5M 4,5 and L2,3M-MM4,5M4,5 transitions are of lower intensity relative to L3M4,5M4,5 transitions when the spectra are excited by CuL X-rays. The relative intensities of these transitions in the spectra excited by CuL and MgK X-rays are compared with calculated transition rates and assumed distributions of the initial L-shell hole population. A component of the spectrum excited by MgK X-rays agrees in intensity and position with theoretical predictions that a band-like feature should occur to high energy of the quasi-atomic L3M 4,5M4,5 group.
