Аннотация:Molecular dynamics computer simulation of the angular distribution of atoms in collision cascades penetrating a surface of (001) Ni (only for atoms later sputtered) shows that for 50–250 eV Ar+ ion bombardment there are no maxima alone <011> directions as might be expected for focused collisions. However, the distribution of sputtered atoms exhibits ejection maxima near <011>, as expected, suggesting strong doubt about the contribution of a focuson mechanism to explain such effects for low energy ion bombardment. The mechanism of focusing of sputtered atoms during ejection from a lattice site at a surface of (001) Ni has been studied.
