High pressure equation of state for solid argon from interatomic potentials
Abstract
The pressure-volume isotherm for solid argon at 298 K is calculated by the Monte Carlo method using the pair potential of Barker, Fisher, and Watts (BFW) together with the Axilrod-Teller (AT) three-body interaction. Comparison is made with recent experimental data of Ross and co-workers extending up to 800 kbar. Agreement with experiment is good though not perfect. Comparison is made with the pair potentials of Aziz and Chen and Koide, Meath, and Allnatt and with the exp-6 "effective" pair potential of Ross. © 1987 American Institute of Physics.
