Time-Dependent Effects Associated with the 50°K Resistivity Anomaly in the Pd–H and Pd–D Systems

The characteristics of the time dependence of the electrical resistivity of Pd–H and Pd–D alloys in the vicinity of the 50°K resistivity anomaly are presented. It is suggested that there is a connection between the time dependence of the resistivity and the exothermic processes observed by others in these alloys at low temperatures, in that both effects are associated with the low-temperature annealing out of lattice damage produced by the transition at 50°K.
