Abstract
The elastic constants of hcp H2 and D2 are calculated for densities up to 10 cm3/mole (∼20 kbar at T = 4.2 K). An Isotropic pair potential is utilized in the computations and cubic anharmonic corrections are incorporated into the lattice dynamics. The results are compared with sound velocity, specific heat, and Brillouin and neutron scattering measurements.
