Abstract:
We have observed electrons ejected from autoionizing levels which lie between the <sup>2</sup>P<sub>3/2</sub> and <sup>2</sup>P<sub>1/2</sub> 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.
