Angular distributions in the double ionization of the noble gases by electron impact

Abstract

A fivefold differential cross section for electron-impact double ionization of Ne, Ar, Kr, and Xe is calculated for an incident energy of about 5.5 keV and low momentum transfer. The calculation is based on the first Born approximation. Correlation is taken into account both in the initial state and in the final state. The results obtained are in reasonably good agreement with the available experimental data. Many other typical situations are investigated in order to identify the best choices of the kinematical parameters for future experiments.
