Abstract
PMR spectra have been recorded and the proton spin–lattice relaxation time has been measured for cubic hydride δ-ZrH2. It is found that above 290 K thermally activated diffusion of hydrogen takes place. In the region 230 K, a reversible phase transition takes place, which is due to a change in the state of hydrogen in the crystal lattice of zirconium dihydride. Possible mechanisms of this transition are discussed.
