Exerting pressure jumps of several kbar in gaseous deuterium in the range of 5-28 kbar, surrounding a palladium deuteride wire, the diffusion coefficients of deuterium in the solid phase were evaluated by following the time course of the electrical resistance. Absorption of deuterium is characterized by a smaller diffusion coefficient than its desorption. Both represent a decreasing function with the inrease of deuterium pressure. The difference of the ab- and desorption kinetics is explained by the influence of the elastic energy on the energetics of the occupation of metallic interstitials by deuterium particles. Comparisons with previous measurements are given.
