Abstract

Models of nonequilibrium-stimulaled diffusion and the release of hydrogen and its isotopes from metals by the action of ionizing radiation are considered. It is suggested that the acceleration of the release of hydrogen from metals by the action of radiation is due to the excitation of nonequilibrium vibrational states in the hydrogen subsystem of the metals and a reduction in the surface potential barrier by the desorbing molecules, It is shown, in particular, that the diffusion coefficient of deuterium in Pd is increased by a factor of 30 by the action of radiation compared with a nonirradiated sample.
