Recent advances in distorted-wave calculations of ion impact single and multiple ionization of atoms and molecules
our most recent calculations of different processes employing the non-relativistic CDW-EIS approximation at intermediate and high energies are presented. These include single and multiple ionization of atoms by ion impact including post collisional processes, and single ionization and electron capture in collisions between ions and molecules of biological interest. We employ the independent electron model, initial and final states that verify the correct asymptotic conditions for Coulomb potentials, and the straight-line version of the impact-parameter approximation, which is valid at high-impact energies.
Recent calculations for single and double ionization of He using a new version of the Exponential Model, modified to treat collisions with highly charged ions, will be also presented.
