Effect of three-body interactions on third virial coefficients of rare gases

Abstract
Third virial coefficients of neon, argon, krypton, and xenon have been calculated using the reliable XC and HFB pair potentials and three-body dispersion energies. Comparison between calculated and selected experimental values shows that the agreement is within the experimental error. The influence of three-body charge-overlap effects and exchange energies on the third virial coefficients is discussed.
