Identification of Auger spectra induced by Ar+ and Kr+ ion impact on transition metals

Abstract

The production of Auger electrons from Cr, Mn, Fe, and Co by 20–200-keV Ar, 100-keV Kr, and 3-keV electrons has been studied. The metal M23M45M45 and the Argon LMM peaks are clearly identifiable, the latter broadened consistent with electron emission from backscattered Argon ions. Various other features are produced which cannot be due to target or projectile Auger emission. These are believed to result from interatomic transitions between the ions of the beam and those of the target.
