X-ray excited Auger and photoelectron spectra of magnesium, some alloys of magnesium and its oxide

KLL, and KLM Auger and X-ray photoelectron spectra for pure magnesium, for Mg 2 Cu, Mg 3 Au and Mg 3 Bi 2 , and for MgO are reported. Assignments are made for almost all of the observed features in the Auger spectra. For the pure metal, internal photoemission peaks and a plasmon gain peak are shown to be present in the X-ray excited spectra.
