Dynamic effective charge in the continuum final state in the CDW-EIS model: ionisation of molecules by bare-ion impact

Abstract

In the present work, we address the problem of single ionisation in ion molecule collisions by implementing the dynamic charge continuum distorted wave—eikonal initial state model. A dynamic charge that depends simultaneously on both the emission angle and the emission energy is used to approximate the non-Coulomb potential of the residual molecular target. The molecular ground state is described employing a complete neglected of differential overlap approximation. The results in terms of total, single, and doubly differential cross sections are calculated and compared with available experimental data. Also, the contribution of each molecular orbital to the total cross section has been considered.
