项目摘要

Interaction of energetic ion beams with solids and materials property change induced under ion-beam irradiatin have long been attracting attention from both points of view of its basic understanding and application. In order to understand the phenomena, a large number of works have already been performed both theoretically and experimentally. However, the process of the interaction and material property change induced under ion-beam irradiation have not yet been fully understood and still remain as a field of fundamental scientific problems, although material modification by ion-beam irradiation has widely been applied in various engineering fields.In this study, Rutherford backscattering and channeling measurements have been applied to investigate both deep radiation damage and depth profile of implanted Au atoms in pure Cu and Cu-1at.% Ni alloy single-crystal specimens, which were irradiated off axis at room temperature by 300 keV Au+ ions to a dose of 2x10^<16> ions/cm^2. The damage range and depth range of the implanted Au atoms in the specimens of pure Cu were strikingly deeper than those in the specimens of Cu-1at.% Ni alloys, respectively. An atom movement mechanism in solids under ion beam irradiation is proposed as the origin of the observed results.
