Abstract

Using a new experimental station to be installed at the HITRAP facility at GSI we studied electron emission yields of Ar13+ ions impinging on a clean Au(1 00) surface. By taking data under different incidence angles and at different initial kinetic energies, contributions from kinetic and potential electron emission are separated. The number distributions of the emitted electrons exhibit signatures of specific trajectory classes contributing differently to the electron emission yields. Support for the identification of the different trajectory classes is obtained from SRIM simulations. (C) 2010 Elsevier B.V. All rights reserved.
