Abstract
Neutralization of low keV ions at a LiF(001) surface is studied in a grazing incidence geometry. The combination of energy loss and electron spectroscopy in coincidence reveals two neutralization channels of comparable importance. Besides the Auger process, the neutralization can proceed via peculiar target excitation, corresponding to the formation of an electron bihole complex termed trion.
