• The recovery process of hydrogen dissolved in excess in thin plate specimens of pure nickel was studied by means of the liquid hydrogen quenching method atnd the electrical resistance measurement which had already been successfully applied to wire specimens of nickel and iron.The recovery stage which appears in the isothermal electrical resistance curves between 200 K and 320 K was quantitatively analyzed by taking account of the diffusion of the dissolved hydrogen atoms to the surface and escaping out of the specimen. Extremely good agreement is obtained between the experiment and calculation. The activation energy of migration, E=9.48kcal/mol, and the pre-exponential factor, D_o= 6.87 x 10^-3 cm^2/sec arc obtained. These values agree with those obtained for the wire specimens, and it is confirmed that the recovery process of excess hydrogen in nickel is purely diffusion controlled.
