We present electron spectra arising from collisions of N[sup [ital q]+]([ital q]=6,7) on a Ni(110) target for different kinetic energies and observation angles. The bulk of the K-Auger electrons are ascribed to emission that takes place below the surface. At very low projectile velocities the K-Auger spectra show a contribution from Auger processes that take place before the projectile has penetrated the surface. These above-surface processes manifest themselves as a narrow peak on top of a much broader sub-surface component.
