The influence of the static potential in high-energy K-shell electron capture collisions

Abstract

A theoretical model based on the CDW approximation of Cheshire (1964) for K-shell electron capture by stripped nuclei from multi-electronic atoms at high energies has been derived. The influence of the projectile-passive-electron interaction has been properly taken into account in addition to the well known nucleus-nucleus interaction. As an application of this model, differential cross sections for H++He(1s2) to H(1s)+He+(1s) are calculated and compared with other recent theoretical and experimental data.
