| Sumario: | A quantum-mechanical (QM) model was used for investigating the emission probability of valence electrons at high impact energies. A precise representation of the electronic interactions was introduced within the binary collisinal formalism. The main features of the metal surface were described using the QM approach that was based on the use of the model potential. The angle and energy diatributions of electrons emitted during the grazing scattering of fast protons on an aluminum surface were determined using the model. Substantial changes in the in the valence emission at low electron energies and intermediate ejection angles were introduced by the realistic representation of the surface that was included in the QM model. |
