Abstract

Photoionization and electron-impact ionization of Xe³⁺ ions in the region of 4d inner-shell excitation autoionization have been studied using interacting-beam spectroscopic techniques. Absolute cross sections for photoionization of Xe³⁺ have been obtained and the electron-impact spectrum has been normalized to previously published absolute data. The Xe³⁺ spectra show large contributions from 4d→nf excitation autoionization processes compared to the lower charge states of Xe due to the significant collapse of the nf wave functions into the ion core as the initial charge state of the ion is increased. In addition, a tentative value for the ionization potential of Xe³⁺ of 42.2±0.2 eV was obtained.
