Abstract

This work is a contribution to the understanding of charge exchange processes during the interaction of ions and atoms with metal surfaces. The charged fractions of deuterium in the case of scattering from a nickel surface and in the case of ion impact desorption of deuterium adsorbed on nickel as well as the charged fractions of nickel sputtered with noble gas ions have been determined as a function of exit energy and angle. The results have been compared with theoretical models. It has been found that most of the measured charged fractions depend exponentially on the inverse velocity component normal to the surface. The charge state fractions of scattered deuterium, however, depend also on the parallel component of the exit velocity. Finally the influence of surface contaminations like carbonoxide and hydrogen have been examined.
