Structure of the Triply Differential Cross Section in the Recoil Region in Relativistic Electron Impact Ionization
Electron impact ionization experiments in which the two outgoing electrons are detected in coincidence after angular and energy analysis have already provided a large body of information in the nonrelativistic energy region (see for instance Lahmam-Bennani 19911 and the articles in (e,2e) and related processes 2. In recent years progress has been made in extending the (e,2e) technique to relativistic impact energies and atomic inner shells using polarized3 and unpolarized electron beams4,5,6 Many of the longlasting discrepancies between experimental results and theoretical data (obtained in various calculations7,8) have been overcome by calculations carried out in the relativistic distorted wave Born approximation (RDWBA) (for a brief overview of the relevant publications see Dreizler et al, this volume9).
