Abstract

Lattice dynamics of γ-ZrH(D) ordered phases with essentially one-dimensional H-H (D-D) interaction was studied by inelastic neutron scattering. The experimental optic peaks were described within the Born-von Kármán model. The bound multiphonon states were observed in the spectra. Their binding energies were derived from the experimental data.
