Abstract

We report inelastic neutron scattering experiments on H and D in β-TaH0.5 and Nb99Ti1H(D)1. On TaH0.5 higher harmonics of the hydrogen vibrations were found up to 400 meV. Qualitatively the observed anharmonicity agrees with recent ab initio frozen phonon calculations on NbH. Spectroscopic results on the impurity system NbTiH(D) allow for the first time a determination of the H-potential for a dilute metal-H- system. The observed anharmonicity is twice as large as in a corresponding hydride phase.
