Abstract The electric mobility of hydrogen and deuterium has been measured at 30/sup 0/C in niobium (Cb) and vanadium by a resistance method. The electric mobility was found to be 5.7 x 10/sup -4/ cm/sup 2//V-s for hydrogen and 2.8 x 10/sup -4/ for deuterium in niobium. In vanadium the electric mobilities were 2.3 x 10/sup -3/ and 1.3 x 10/sup -3/ cm/sup 2//V-s for hydrogen and deuterium, respectively. The effective charges calculated using reported diffusion coefficients are positive and are slightly greater for deuterium than for hydrogen in both vanadium and niobium. The resistivity increase due to the hydrogen isotopes in vanadium and niobium was also measured. Hydrogen was found to contribute 0.65 ..mu.. ohm-cm/at. % and deuterium 0.58 ..mu.. ohm-cm/at. % to the resistivity of niobium. In vanadium, the solute resistivities were found to be 0.98 ..mu.. ohm-cm/at. % and 0.90 ..mu.. ohm-cm/at. % for hydrogen and deuterium, respectively.
