Charge-State Dependence of Electron Loss from H by Collisions with Heavy, Highly Stripped Ions

Abstract

Theoretical calculations, confirmed by experimental measurements, are used to obtain a new scaling rule for electron loss from a hydrogen atom in collision with a heavy, highly stripped ion. The calculations cover the energy range 50 to 5000 keV/amu and charge states $q$ from 1 to 50. The experiments are in the range 108 to 1140 keV/amu and charge states 3 to 22. A simple analytic expression that describes the electron-loss cross section for $1<~q<~50$ in the energy range 50 to 5000 keV/amu is presented.
