✦ Synopsis

A simple phenomenological theory of liquid-sold phase transitions, based on the use of perturbation theory about a hard-sphere fluid, is examined. A temperature dependent hard-sphere diameter is determined which permits the prediction of solid and liquid densities and melting pressures. Calculations presented here for the Lennzrd-Jones 12-6 fluid show good agreement with the computer simulation results. Provided pair potentids are availrrble, the theory may also be used for other fluids, including liquid metals.
