Abstract

The β - and γ -phases of titanium hydride were studied by inelastic neutron scattering(INS). Biphonon and triphonon excitations were clearly observed in the y-phase as distinct peaks split from two-phonon and three-phonon bands to lower energies. Bound multiphonon states seem to occur also in the < γ -phase, they appeared in the INS spectra as hump-shaped features at the low-energy side of the free multiphonon bands.
