Electron transfer in keV collisions: II. Molecular basis model

Abstract

The velocity dependence of state-to-state integral cross sections for electron transfer and excitation in collisions is studied in the 0.05 - 0.3 au velocity range using the impact parameter semi-classical method and a 28-state molecular orbital basis model including a common translation factor. The initial orbital alignment dependence of electron transfer is in fair agreement with recent experiments and with atomic orbital model calculations. The main electron transfer channel from is to the states. The integral cross sections from an aligned or oriented state to an aligned or oriented state and vice versa and the corresponding alignment and orientation parameters are presented as a function of the impact velocity.
