چکیده انگلیسی
A classical dynamics simulation of the low energy He+ ion scattering on a Cu(100) surface was carried out for a more detailed explanation of LEIS azimuthal scans with respect to a previous work. The Thomas-Fermi-Molière screened potential was used in the calculations to describe interatomic repulsive interactions. A stopping power and thermal vibrations of target atoms were involved as well. The results of the simulations were compared with the experiment and thus the correction factors of interatomic scans found. The main features of the calculated azimuthal scans N(Φ) are discussed and the relevant parts compared. Additionally, ion blocking effects were studied by the analysis of NΦ,β distribution of ions backscattered into the whole half-space above the Cu(100) surface. This gave us a more transparent view into the low energy ion scattering processes on this periodic surface.
