Abstract
Neutralization of low keV Ne+ 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 Ne+ neutralization can proceed via peculiar target excitation, corresponding to the formation of an electron bihole complex termed trion.
