THE RELATIVE IMPORTANCE OF ELASTIC AND INELASTIC-SCATTERING IN ANGLE-RESOLVED AUGER-ELECTRON SPECTROSCOPY - A RESPONSE

The importance of elastic scattering and interference in creating the modulation observed in angle-resolved Auger electron spectroscopy is discussed, along with the conceptual similarity between the scattering of Auger and photoelectron waves. While inelastic scattering is certainly important, the angular dependence of the associated cross sections is considerably less pronounced than that associated with elastic scattering. These results, which have been firmly established in the past decade, are at odds with recent claims by Frank et al. (Frank, D. G.; Batina, N.; McCargar, J. W.; Hubbard, A. T.
