Under a continuous charging of deuterium by rf plasma, depth profiles of trapped deuterium in nickel, which was prebombarded with 0.9 MeV H3+ions, were examined by means of a nuclear reaction D(3He, p)4He analysis. There was an equilibrium between the dissolved deuterium and the trapped one. From the equilibrium constant observed in the temperature range of 398 to 621 K, the enthalpy difference between the dissolved deuterium and the trapped one, i.e. the trapping energy, was obtained to be 0.22 eV. The value was the same as that obtained for the4He+prebombarded case. The depth profile of the trapped deuterium was similar to the estimated distribution of atomic displacements. The trap was associated with radiation-induced defects. © 1995, All rights reserved.
