Stage IV Recovery of Platinum after Electron Irradiation

Abstract
The activation energy of the stage IV resistivity recovery after electron irradiation of platinum has been measured to be 1.36±0.08 eV. The recovery is due to the migration of single vacancies. A model of diffusion to inexhaustible internal sinks, complicated by a vacancy-impurity trapping interaction, is found to describe the platinum recovery data. In addition, the stage IV recovery of deformed nickel is found to follow the same recovery model.
