Vibrationally-resolved charge transfer between O$^+$ ions and H$_2$ molecules

POSTER

Abstract

The non-dissociative charge transfer process O$^+$ + H$_2$ (v) $\to$ O + H$_2^+$ (v') has been investigated using the quantal molecular-orbital coupled-channel method. Vibrationally-resolved total and electronic state-selective cross sections based on the infinite order sudden approximation (IOSA) and the electronic approximation (EA) will be presented for relative collision energies from 0.1 to 1000 eV/u. The IOSA and EA results will be compared to the limited previous theoretical work and to the wealth of experimental data for both ground and metastable incident oxygen ions.
