Abstract
Abstract The computer simulations of ion scattering by some rarefied infinite atomic chains and some broken chains, consisting of a finite number of atoms, taking into account correlated thermal vibrations and two types of interaction potential were carried out. It was shown, that the increase both of the interatomic distances and the amplitude of thermal vibration and also the potential cut-off, results in an increase of the size of loops in the energy-versus-scattering angle diagram, that explains the scattering in the observed directions, shadowed in case of ideal chain. The calculations allow the establishment of the correlation between the type of surface defect and the shape of the energy spectra.
