Collision processes using effective potentials

Abstract

We investigate the feasibility of using pseudopotentials to generate the bound and continuum orbitals needed in collisional calculations. By examination of several inelastic processes in the first Born approximation, we demonstrate the inconveniences of this approach. Instead, we advocate use of effective potentials obtained with the depurated inversion method (DIM). In this contribution, we extend this method to molecular systems. Calculations of single first-order photoionization and proton-impact ionization using the DIM show fair agreement with experimental results for both atoms and molecules.
