Abstract
Measurements of the electrical resistivity of palladium–hydrogen and palladium–deuterium alloys between 4 °K and room temperature, for concentrations between 0 and 0.62 atomic ratio for each alloy, are presented. These results show an anomaly in the resistivity of the Pd–D alloys in addition to the one in the Pd–H alloys previously reported by Schindler, Smith, and Kammer at essentially the same temperature. Some hysteresis has been observed in the resistivity of the alloys as a function of concentration.
