| Abstract: | The azimuthal and polar angle distribution of Ni+ and Mo+ ions emitted from an ordered Ni4 Mo single crystal irradiated with 10-keV Ar+ ions was studied. Different azimuthal distributions for Ni+ and Mo+ ions emitted from the (001) Ni4Mo face were detected; emission maxima were observed in 〈 011 〉 and 〈 001 〉 directions for Ni+ and Mo+ ions, respectively. It was shown that polar distributions of nickel’s secondary ions vary with its energy. The observed systematic features were explained by correlated collisions in the upper layers of a Ni4Mo single crystal. |
