Dependence of the survival fraction of reflected molecular ions on the mutual disposition of atomic rows on the surface of a crystal

A comparative analysis is performed of the orientational effects with reflection of molecular nitrogen ions with an energy of 30 keV from the (100) and (110) facets of a copper crystal. It is established that the nature of the characteristics of the survival fraction is not a function of the crystallographic direction, but is determined by the nature of the mutual disposition of the atomic rows on the surface of the crystal.
