Charge Transfer and Dissociation in Cq+ + H2 Collisions

Abstract

We present calculations of charge transfer cross sections for Cq+ + H2 collisions with q = 2, 3, 4 in the energy range 50 eV/amu < E < 2.5 keV/amu. We employ ab initio electronic wavefunctions of the triatomic systems, the eikonal method to treat the ion-diatom relative motion, and the sudden approximation for vibration and rotation of the diatom.
