The specific heats of neon and xenon are calculated from a study of their lattice vibrations. The effect of zero‐point energy is included by an iterative method and a Buckingham exponential potential is used. The calculated and experimental values of C v agree well for xenon but not so well for neon. It is suggested that the interatomic forces in neon are similar to those in helium and that a Buckingham potential, which is applicable to solids formed from heavy rare gases, is inapplicable to solid neon.
