Abstract

It is shown that a law of corresponding states exists amongst the inert gases in the solid phase even when quantum effects are large. The theoretical treatment is based on the Einstein model of a crystal modified to account for large vibrations of the crystal atoms. Using a Lennard-Jones 12-6 potential for the interaction energy between a pair of atoms, reasonable agreement is obtained between theoretical and experimental values for the equilibrium volumes and energies of the rare gas crystals at the absolute zero.
