Kinetic-energy transfer in highly-charged-ion collisions with carbon

Abstract

We present an accurate theoretical model for the charge dependence of kinetic energy transferred in collisions between slow highly charged ions (HCIs) and the atoms in a carbon solid. The model is in excellent agreement with experimental kinetic-energy-loss data for carbon nanomembrane and thin carbon foil targets. This study fills a notable gap in the literature of charged-particle energy loss in the regime of low incident velocity (${v}_{p}\ensuremath{\lesssim}2.188\ifmmode\times\else\texttimes\fi{}{10}^{6}$ m/s) where charge states greatly exceed the equilibrium values.
