Elastic and Inelastic Scattering of Low-Velocity H+ and H2+ in Hydrogen

Abstract

Cross sections have been measured in the energy range 4 to 400 ev for elastic scattering and charge exchange of H+ and H2+ ions in hydrogen. The results are compared with similar measurements for deuterium ions in deuterium. Charge exchange was observed over the entire energy range for H2+, but was detected only above 50 ev for H+. Constants for empirical potential functions have been evaluated and are tabulated.
