Abstract

One area in atomic and molecular physics that computer modelling and its applications are extensively used is in ion-atom collisions. In this paper we consider computer simulations for various theoretical continuum-distorted-wave eikonal-initial-state (CDW-EIS) models used in the study of single ionization of neutral target atoms by fast highly charged ions. In our first study we examine ultra-low energy electrons for 3.6 MeV amu-1 Au53+ on helium, neon and argon. Doubly differential cross sections as a function of the longitudinal electron velocity for various transverse velocity cuts are obtained using the CDW-EIS model. A sharp asymmetric peak centred at a longitudinal velocity of zero is observed to emerge at ultra-low energies in all of the collisions studied.
