Abstract
Al ${\mathit{L}}_{2,3}$VV auger-photoelectron coincidence (APEC) data are presented and discussed. The well-known ability of APEC to suppress inelastic-scattering contributions to Auger and photoelectron spectra is used to demonstrate that much of the large low-energy tail common to core-valence-valence Auger spectra from many wide-band solids is not due to secondary-electron scattering, but, rather, is an intrinsic part of the core-hole-decay process.
