Nuclear magnetic resonance study of the metal-nonmetal transition in lanthanum hydrides

Creators

Description

Proton spin-lattice relaxation time (T1) measurements have been used to investigate the metal-nonmetal (MNM) transition in the lanthanum hydride system, LaH/sub x/ (2 ≤ x ≤ 3), on samples prepared from highest purity Ames Laboratory lanthanum and also from the same lanthanum doped with controlled low levels of gadolinium. The dependence of hydrogen diffusion parameters on hydrogen concentration x was also determined. 77 refs., 51 figs., 4 tabs
