Abstract
The annealing in stage III and IV of irradiated, and quenched plus irradiated Pt samples has been studied in detail. At low defect densities the observed activation energy is equal and constant in both stages and amounts to 1.4 eV. At higher irradiation induced and quenched in defect densities, a systematic variation of the effective activation energy is observed in both stages. A model which assumes vacancy migration in stage III and stage IV and which allows for partial formation and more rapid migration of divacancies is able to account for these experimental observations. Model calculations using physically reasonable values for the relevant physical parameters are able to reproduce quantitatively the experimental recovery curves and activation energies.Keywords
