Abstract
We have calculated the energy distribution of electrons produced by io nization of bulk electrons in grazing H+ surface collisions. In this f irst approach we assume a direct ion-surface Coulomb interaction, desc ribe the solid within the jellium approximation, and consider nonparal lel ion trajectories near the surface. In agreement with experimental results, the energy distributions present a maximum around 3 eV, stron gly dependent on the observation angle and projectile energy.
