The traditional theme of metal hydride transport analysis has employed an equation for the probability P l (t) that a hydrogen atom occupies an interstitial site l in the host metal at a time t1
$$\frac{d}{{dt}}{P_\ell }\left( t \right) = {\Sigma _{\ell '}}\left[ {{\Gamma _{\ell \ell '}}{P_{\ell '}}\left( t \right) - {\Gamma _{\ell '\ell }}{P_\ell }\left( t \right)} \right] $$
where Γ ll is the hopping rate from site l’ to site l. The inadequacy of such treatments has led more recent investigations to con-sider correlations between jumps and correlations in continuous time.2 We will discuss here a transport instrument particularly well suited to the analysis of such memory effects, and we will illustrate the nature of these effects on the quasielastic scattering function.
