Resonance charge transfer between protons and excited hydrogen atoms I. Quantal two-state approximation

Abstract

Using the quantal two-state approximation the cross sections for symmetrical resonance charge transfer between protons and excited hydrogen atoms (with principal quantum number 5 or less) are computed. Allowance is made for the effect of the change in the velocity of relative motion during the encounter. In most cases this correction is appreciable if the impact energy is less than about 25 ev.
