Abstract
Thermodynamic properties and elastic constants of solid argon have been calculated using an accurate pair-potential together with the Monte Carlo method and the Axilrod-Teller three-body potential. Excellent agreement is obtained with experimental values of the pressure and internal energy. However the calculated elastic constants show systematic deviations from the experimental values. These discrepancies are examined in some detail and possible reasons for them are given.
