Detailed assignment of normal and resonant Auger spectra of Xe near the L edges

Abstract

<div lang="en" class="abs"><p class="abs_header">Abstract</p><p>We present a comprehensive experimental and theoretical investigation on the LMM, LMN, and LNN normal Auger spectra of xenon, which reveal excellent agreement with theory when core-hole lifetimes of the two-hole final states are taken into account. Generally, the spectra turned out to be highly complex due to a strong overlap of the Auger transitions subsequent to 2s1−/12, 2p1−/12, and 2p3−/12 ionization. This overlap is due to the splitting of the three initial L core holes and the different final M and N core holes being on the same order of magnitude of several hundred eV. The Auger transitions are assigned in detail based on the theoretical results. Most of the MM, MN, and NN final states are described well based on jj coupling. In addition, we present a detailed assignment of the resonant LM45M45 Auger transition subsequent to the 2s → 6p, 7p and 2p → 5d, 6d excitations.</p></div>
