Charge transfer for He²⁺on H using molecular bases with plane wave translational factors

Abstract

Theoretical He+(2s) and total charge transfer cross sections for 1 to 70 keV 4He2+ ions incident on H(1s) atoms are reported. Results obtained using molecular bases with and without plane wave translational factors (the latter in the frames of reference having as fixed origin the He nucleus, and several selected points between the nuclei) are contrasted.
