| Abstract: | We report on X-ray Bragg intensity measurements in the high concentration range of NbHx and VDx as a function of temperature andH(D) concentrationx. The mean square thermal displacements of the metal atoms decrease with increasingH(D) concentration. For concentrations higher thanx 0.7 a sharp increase was observed. The metal lattice first stiffens withH(D) dissolution and then becomes very soft. |
