Abstract
Protons with energies ranging from 5 keV to 710 keV are scattered from an Al(111)-surface under a grazing angle of incidence. The scattered beams are analyzed with high angular and energy resolution with respec t to the energy loss of the projectiles. We observe a linear increase of the energy loss with velocity up to upsilon approximate to 1.5 a.u. (about 50 keV) and a subsequent constant loss of about 3 keV for high er velocities (energies). The data show a very weak dependence on angl es relevant for the scattering event.
