Abstract
ACO synchrotron radiation has been used to obtain photoelectron spectra of the outer shell of xenon in the 75-100 electron volts energy range. Satellite peaks corresponding to the formation of excited ionic states have been observed, in addition to the main peaks corresponding to the production of the 5s2 5p5 2P and 5s 5p6 2S states of Xe+. A comparison is presented of the intensities of the satellites relative to the main lines for different energies of the incident radiation. There are several ways to excite satellite lines, via core rearrangement, virtual super Coster-Kronig processes, ground state correlation and final state cattering processes involving the primary photo- electron. In this paper we present theoretical calculations involving one particular process, namely virtual Coster-Kronig process, which gives good agreement with experimental 5s binding energy and gives the correct order of magnitude for the relative intensities of the satellites corresponding to
