| Abstract / Description: | Absolute experimental measurements have been reported for the fully differential cross section (FDCS) for single ionization of helium by 3.6 MeV/u AuQ+ (Q = 24, 53) ions. These absolute measurements are not in very good agreement with CDW-EIS (Continuum Distorted Wave-Eikonal Initial State) calculations which are normally in excellent agreement with doubly differential cross section measurements. We have recently introduced the 3DW-EIS approach which is a fully quantum mechanical approach. In addition, we have used a Hartree-Fock distorted wave for the outgoing electron instead of approximating the ejected electron as a Coulomb wave with an effective charge. For the case of low energy C6+ ionization of helium, the 3DW-EIS results were shown to be in better agreement with absolute experimental data than the CDW-EIS approximation. The purpose of this paper is to investigate the validity of the 3DW-EIS model for more highly charged ion. |
