Transfer ionization in He²⁺-H^-collisions: cross section measurements in the energy range 0.2-1300 eV

Abstract

This paper reports on measurements of the cross section for transfer ionization in He2+-H- collisions over the barycentric energy range 0.16-1300 eV. The experimental method involves merged beams and coincident detection of the reaction products. The dependence of the cross section on the energy is rather similar to that of the one-electron exchange, suggesting that a two-step mechanism dominates the process.
