Abstract

The dissociative charge transfer reactions between He+ and CO2 at high translational energies (0.1-5 keV) have been modelled by a simple two-state treatment. The total electron transfer cross-section is in quantitative agreement with experiment. Curve crossings at 1.7-3.05 Å lead to He and CO+2 in highly excited electronic states. These products of charge transfer, if formed on the incoming channel, may then undergo an excitation or de-excitation crossing at 1.4-2.0 Å during the evolution of a single-collision event, to form the observed products of reaction. Stueckelberg-Demkov non-crossing behaviour does not appear to be important in this reaction system. © 1989.
