摘要：

Using a triple-axis neutron spectrometer all branches of the phonon dispersion curves along the three major axes of zinc have been measured. The results for the Δ and Σ axes are in fair agreement with those of previous workers. Results for the T, Tprime axes have not previously been reported. All results have been fitted by a model with seventeen independent interatomic force constants. Though the fit to the measured phonons is adequate, the agreement with elastic constants is quite unsatisfactory. The more basic pseudopotential models cannot fit the data.
