Abstract
Elastic constants from Monte Carlo computer experiments are compared with values calculated by self-consistent phonon theory for a model approximating fcc solid Xe. We have used a Lennard-Jones (12-6) nearest-neighbor potential which gives a fair account of the thermodynamics. Adiabatic elastic constants obtained by both methods are in good agreement. Comparison is also made with recent experimental elastic-constant data of Gornall and Stoicheff.
