Abstract

A central force lattice dynamical model, previously applied by Slaggie to the CaF₂ structure of ZrH₂, is extended to the BiF₃ structure. It is used for the analysis of inelastic neutron scattering data on cerium hydrides CeH_1.98 and CeH_2.72. For both samples the force constants are derived. The values of the corresponding force constants in both hydrides are different. The additional hydrogen in the CeH₂ structure is found to be weakly bound.
