摘要：
The effect of atomic ordering on the angular distribution of the sputtering of the (001) face of a Ni4Mo single crystal irradiated with 10-keV Ar ions is studied using molecular-dynamics simulation and experimentally. It is shown that, in the case of a disordered crystal, both the Ni and Mo components are ejected in the same crystallographic direction. In the case of an ordered crystal, Mo emission is observed in the same directions, and the Ni emission deviates from them. The results are compared with data obtained for secondary ion emission from the Ni4Mo (001) face.
