Experimental procedures for the determination of superdiffusion coefficients ofhydrogen in L.-metals (V, Nb, Ta) under external tensile stress parallel to (111')>aredescribed in detail. Results are analyzed in the light of the lattice activated tunnelingtheory. The activation energy E. and the tunneling matrix element l J l are obtained experimentally as follows:7'.[meV]: 21 for V, 15 for Nb, 12 for Ta,andJl [meV]: 0.44 for V, 0.085 for Nb, 0.065 for Ta.The superdiffusion mechanism of hydrogen in these metals is theoretically discussed.
