Low-velocity stopping of heavy ions

View publication

Abstract

The apparent discrepancy between theory and experiment in low-velocity electronic stopping of heavy ions is shown to be resolved for several representative cases by taking into account the velocity dependence of both the effective charge of the ions and of the atomic stopping power for fixed ionic charge. A new formula for the electron density dependence of the stopping number is introduced, based on recent work by Vager and Gemmell.
