| Abstract: | Abstract Time-dependence ‘in situ’ measurements of the electrical resistance of Ni-30at.%Cu under H2/D2 atmosphere up to about 1.2 GPa show a faster formation of the deuteride than of the hydride. This corresponds to a higher diffusivity of the heavier isotope. The effect, being in contrast to the classic rate theory, agrees in tendency with experiments in case of Pd-H/D and with treatments of the quantumstatistic theory. |
