Monte Carlo Study of the Elastic Constants of Compressed Ar

A Monte Carlo calculation of the elastic constants of solid Ar at 80 ^∘{}K and near zero pressure has been reported by Klein and Murphy. This calculation employed the Bobetic-Barker Ar₂ pair potential and included a correction both for three-body forces and quantum effects. The present note extends the previously calculated elastic constants to include the volume dependence at 80 ^∘{}K and the temperature dependence at 21.99 cm³ mole^-1. Comparison is made, where possible, with the scant experimental data.
