Abstract
The lattice dynamics of the ordered gamma-TiH(D) and gamma-ZrH(D) phas es with essentially one-dimensional H-H (D-D) interaction have been st udied by inelastic neutron scattering. The bound multiphonon states (b iphonon, triphonon, tetraphonon and their combinations) were observed in the spectra, and the binding energies were obtained from the experi mental data.
