The Salter vapor pressure equation revisited: a new estimate of the anharmonic effects in rare gas solids

Abstract

The Salter equation for the vapor pressure of a monatomic crystal was applied to the data of Chen et al. The relative magnitudes of the terms were re-examined and the importance of the Debye and anharmonic terms were noted. New values of the anharmonic coefficients were determined by adjusting these until the derived values of the static lattice energy matched ones calculated on the basis of recent potentials.
