Electron Impact Excitation of Autoionizing Levels of Kr and Xe Between the ²P_3/2 and ²P_1/2 Ionic Limits

Abstract

We have observed electrons ejected from autoionizing levels which lie between the ²P_3/2 and ²P_1/2 ionic limits for Kr and Xe. Kinetic energy spectra of the ejected electrons were obtained following electron impact excitation of the target gases by using time-of-flight spectroscopy in a crossed beam experiment. Spectral features which correspond to electrons ejected from both odd and even parity autoionizing levels have been identified.
