Single-Particle Theory for Systems at High Densities. III. Solid Neon and Some Considerations of the Second Virial Coefficient

A quantal version of the Lennard-Jones and Devonshire cell model is used to predict the thermodynamic properties of solid neon. As was observed previously for solid argon, good agreement with experiment is obtained if the parameters of the assumed 12:6 pair-potential are calculated from zero-point crystal data. In view of the success of the application of this theory to the solid state, second virial coefficient data are interpreted using the zero-point reduction parameters. Again a satisfactory comparison of experiment and theory is observed.
