Abstract
The migration of hydrogen in Lu is determined by electrical resistance measurements in temperature range of 140-170 K. Disordered hydrogen a toms, which ard formed by quenching, migrate to order during annealing in the above temperature range. The rate of the resistance decrease d epends on the ordering rate of hydrogen. From the resistance decrease during isothermal annealings, the activation energy of hydrogen migrat ion is determined as 0.43 eV (41.5 kJ mol(-1)).
