Abstract

Measurements of the retention of deuterium in polycrystalline nickel have been obtained at 193 and 223 K through elastic-recoil detection using a 2.6MeV4He beam. The depth profiles obtained show striking differences from their counterparts measured at higher temperatures. Although the profiles are homogeneous at implanted fluences lower than 3 x 1.0 E18 D(+)/cm2, they present a large peak centred slightly deeper than the implantation range at higher fluences. Additional features develop as one implants further. The large peak is associated with the buildup of nickel deuteride. A one-dimensional computer model is developed which partly reproduces the features of the measured depth profiles.
