Abstract
Protons with energies ranging from about 6 to 30 keV are scattered und er grazing angles of incidence from a flat and clean Al(111)-surface. We observe angular and energy distributions of the scattered projectil es with high resolution and find for the mean energy loss a pronounced increase with projectile energy and a slight decrease for an increasi ng angle of incidence. We present model calculations based on the assu mption that the energy loss is predominantly due to binary collisions with conduction electrons. These calculations reproduce main features of our data fairly well.
