摘要：

Elastic constants and phonon dispersion curves for crystalline argon at low temperatures are calculated using the accurate pair potential function developed by Bobetic and Barker together with the Axilrod-Teller three-body interaction. The phonon dispersion curves are in good agreement with experiment, but the elastic constants show substantial differences from current experimental estimates.
