Abstract

We have investigated electron emission for impact of slow multiply charged Ar ions on an atomically clean and flat insulating LiF(001) surface. Time-of-flight spectra and the number of emitted electrons have been determined in coincidence for grazing scattering of Ar^q+ projectiles from LiF. By relating projectile energy loss to kinetic electron emission we were able to determine contributions from potential electron emission even in the presence of a considerable number of kinetically excited electrons.
