(e, 2e) angular distributions and energy spectra in cadmium

Existing (e, 2e) angular distribution measurements and (e, 2e) energy spectra in atomic cadmium are reviewed and a major difference in the analyses of the two data sets is highlighted. It is shown that an autoionizing level, previously postulated to explain the angular distribution data, does not exist, and is an artefact of the simplifying assumptions used in the original analysis. A new calculation is presented which unifies the interpretation of the measured angular distributions and the energy spectra.
