Abstract
The population of NaI 3p- and 4d-terms after grazing collisions of fast Na+-ions with a clean Al(111)-surface is studied via optical spectrometry. The ratio of level populationsN(3p)/N(4d) is investigated in dependence on projectile velocity under different experimental conditions. For clean targets and a defined geometry of detection a threshold for excitation of the 4d-term is observed. The data are described by a model of population via resonant one electron tunneling which incorporates the effects of the projectile velocity.
