Abstract
Inelastic neutron scattering has been used to measure the phonon energy dispersion relation along the (001), (110) and (111) directions of a single crystal of lead fluoride, PbF2, at 10K. Shell model parameters have been successfully fitted to the data, and those giving the best fit have been used to calculate the density of phonon states and values for the elastic constants and the Debye temperature. The results are compared with data obtained by other methods.Keywords
