Resumen:
We have calculated the energy distribution of electrons produced by ionization of bulk electrons in grazing H+ surface collisions. In this first approach we assume a direct ion-surface Coulomb interaction, describe the solid within the jellium approximation, and consider nonparallel ion trajectories near the surface. In agreement with experimental results, the energy distributions present a maximum around 3 eV, strongly dependent on the observation angle and projectile energy.
