Quantum Crystal Effects in Solid Hydrogen at Zero Temperature

Using our theory of correlation effects in quantum crystals, which was originally developed to calculate the properties of solid helium, we obtain the ground-state energy and pressure of solid hydrogen for molar volumes in the range 24-10 ${\mathrm{cm}}^3$. The results are applied to a determination of the effect of zero-point motion on the intermolecular interaction and on the $\lambda$-transition temperature. The crystal field is also discussed.
