Abstract
The energy loss of fast protons, with energy E > 100 keV, specularly r eflected on a solid surface with glancing angle of incidence of the or der of a mrad is analysed on theoretical grounds. Two different contri butions can be distinguished: i) energy losses originating from the in teraction with the valence band, accounted for through an induced forc e, and ii) the excitation of electron bound states of the target atoms . The results are compared with available experimental data.
