The experimental and computer studies of the double-scattering effect for polycrystals

Abstract The effect of double scattering of 10–35 keV Ar ions by a copper polycrystal has been studied in the case of asymmetric reflection. Contributions from collisions of various multiplicities to the obtained energy spectra have been analysed theoretically. The spectra are computer-calculated using the statistical trial method with due account for a discrete set of possible distances between the surface atoms which scatter the ions. The charge-exchange processes are also included in the calculations.
