ERDA ANALYSIS OF THE DEPTH DISTRIBUTION OF DEUTERIUM IN ION-IRRADIATED NICKEL

Abstract Elastic recoil detection analysis (ERDA) using 16 MeV 16 O 5+ ions as a probe, was applied to measure depth distribution of implanted deuterium in polycrystalline nickel specimens. Depth distribution of deuterium in helium pre-irradiated nickel at room temperature was in good agreement with the calculated damage distribution induced by the deuterium and helium ions, while no adequate correlation of deuterium distribution with radiation induced defects was observed in the specimens implated with only deuterium. It was found that deuterium can easily migrate at room temperature in helium non-irradiated nickel. It was suggested that the implanted deuterium was trapped in the helium associated damage.
