Ab initio study of valence correlation satellites in photoelectron spectra of neon

Abstract

Ab initio calculations of energies and widths of the valence correlation satellites in the binding energy region between 48 and 99 eV of the photoelectron spectrum of neon are presented. The results are compared with the high-resolution, synchrotron radiation excited valence photoelectron spectra recorded by Kikas et al. [ J. Electron Spectrosc. Relat. Phenom. 77 (1996) 241] using photon energies of 96 and 169 eV and with previous synchrotron radiation and conventional radiation studies. Our calculations allow a deeper insight in the regions where a bunch of states, different in spin and angular momentum, are concentrated, and add considerable information on assignment and width of several transitions. The theoretical spectrum calculated in the region between 74 and 94 eV compares quite well with the experimental one.
