Abstract: In this paper, some interatomic potentials in studies of the interaction of energetic particles with solid targets are presented, the methods and results of approximate calculations of scattering angle for binary collision in crystalline and amorphous solids are given. The obtained conclusions is significative for computing axial blocking dips, surface peak intensity as well as sputtering by using Monte Carlo simulation.

Key words: binary collision, interatomic potentials, scattering angle, approximate calculations
