Abstract |
The two-parameter Multi-Sublattice Jump Diffusion Model (MSJD), presented in Part I [1], is applied to Hydrogen diffusion in the α-phase of Nb-H. It is proved, mainly on the the basis of quasielastic neutron scattering experiments on a single crystal of NbH 0.09 [2] at T= 510 K, that diffusion occurs as a result of jumps between adjacent and second nearest neighbor tetrahedral interstitial sites.
