Experimental Verification of the Line-Shape Distortion in Resonance Auger Spectra

Abstract
When the mean excitation energy and the width of a broad photon band are varied the Kr 3d5/215p4p25p resonance Auger electron lines show strong asymmetry and their average kinetic energies shift. Even extra peaks appear. Our results demonstrate experimentally, for the first time, that the incident photon energy distribution has very crucial importance on the resonance Auger line shape and thus on the reliable data analysis of complicated Auger spectra.
