摘要：

The phonon density of states g(E) of solid parahydrogen is determined from the inelastic incoherent neutron scattering and total cross-section versus energy measurements at pressures up to 1.06 GPa. The very anharmonic phonon spectra with long ''tails'' and integral parameters versus density were obtained. The role of zero-point vibrations in lattice dynamics of p-H-2 quantum crystal remains significant in the investigated region, over which its density is almost doubled.
