Abstract
Spin-lattice relaxation time (T1ρ) of hydrogen in TiH1.81 and TiH1.90 was measured as a function of temperature yielding hydrogen diffusion parameters. The activation energy is equal to 11.7±0.3 kcal/mole over more than six orders of magnitude of the jump frequency with a break occurring in the Arrhenius relation at 270 K. Discrepancies were found in the preexponential factor and the conduction-electron relaxation times as measured by T1 and T1ρ.
