Abstract

We present K-Auger spectra arising from collisions of hydrogenic C, N, O, F and Ne ions with p-conducting Si(100), Ni(110) and polycrystalline W surfaces for different beam energies and observation angles. These spectra exhibit sharp peaks which, using Hartree-Fock atomic structure calculations, can be assigned to distinct projectile states prior to KLL decay. Moreover, we find that the measured spectra show target-specific features which can be explained by different free electron densities in metals and silicon.
