State-selective electron capture in collisions of ground and metastable O2+ ionswith H(1s)

Abstract

An ab initio calculation of the electron capture cross sections for collisions ofground and metastable states of O2+ with H(1s) is presented. For impact energiesbetween 0.125 and 3.4 keV amu−1, we find good agreement between the crosssections from the ground state ion with the mixed beam experimental data ofPhaneuf et al (Phaneuf A, Alvarez I, Meyer F W and Crandall D H 1982 Phys.Rev. A 26 1892).
