Electron Impact Ionization of Cadmium for Energies near Autoionizing States
Abstract
The process of electron impact ionization of atoms, normally called (e,2e), has been studied for three decades. Most of this work has concentrated on energies far from autoionization resonances. However, for electron energies corresponding to an autoionization resonance, it is not possible to distinguish electrons which have been directly ejected from the atom from those which were first excited to an autoionizing level and subsequently ejected. As a result, these two processes will interfere and the interference can potentially be sensitive to different physical effects than the normal (e,2e) process far from resonances. We will examine (e,2e) for cadmium in the energy range of autoionizing levels. First order plane-wave and distorted-wave results will be compared with recent measurements.
