Abstract

Abstract The radiation-enhanced self-diffusion coefficient D rad in silver under 270 keV proton bombardment has been measured over the temperature range from 240° to -60 °C. The flux dependence of D rad has also been studied at 106° and 179 °C with the flux varying from 2.5 × 10 12 to 6.3 × 10 13 protons/cm 2 sec. The experimental data are analyzed in the framework of the classical model involving single vacancies and interstitials as mobile defects.
