The neutralization rate of He + and the de-excitation rates of excited He atoms in front of an Al surface are computed. This is achieved by evaluating the transition of electronic eigenstates of the He + -Al system to the He + core hole while producing surface excitations. These surface excitations are computed in a self-consistent way. The present work accounts for the full many-body excitation of the metal surface as well as the hybridization of the He-Al orbitals. This hybridization leads to a new qualitative picture of the Auger processes in which the neutralization and de-excitation processes are mixed.
