Abstract
The lattice dynamics and the elastic constants of solid helium at the molar volume of 16 cm3 have been calculated with twelve second order parameters using Keating's approach. The agreement between theory and measurement is as good as that of Reese et.al. who have used the MAS model with eighteen parameters to fit their dispersion data. © 1972.
