Abstract : The quantum correction has been expressed as a deviation eta from RT in Q sub c where Q sub c is the classical partition function. Changes in volume, energy, specific heat, etc., caused by quantization can be expressed in terms of eta and certain thermodynamic quantities. Eta itself is expressed in terms of thermodynamic quantities. The equations obtained give for solid neon the same results, within the limits of error, as the usual treatment of a Debye solid with the aid of the Gruneisen equation. To apply the equation to liquid neon, various thermodynamic quantities have been obtained from known values for argon by use of the law of corresponding states. The difference in volume and specific heat of liquid neon from the values expected from the law of corresponding states has been computed and found to agree reasonably well with the observations. However, the melting point and the delta E and delta S of fusion are found experimentally to be much closer to the classical values than one would expect from the theory. No explanation of this discrepancy is apparent.
