摘要：

An in situ X-ray diffraction study of the high-pressure zeta-phase evidenced a fct Ti sublattice. In the fco chi-phase quenched under pressure, H atoms are displaced to octahedral sites, and the energy of H optic peak (at similar to 75 meV) is half that in other Ti-H phases where H occupy tetrahedral sites. Phase transformations on heating of chi-TiH(D)(similar to 0.75) were studied by neutron diffraction, small angle and inelastic neutron scattering (INS). Bound multiphonons were observed in the INS spectra of ordered gamma-TiH(D).
