Abstract

The zero-point properties of the inert-gas solids are used to determine the parameter values for a range of m:6 Kihara core pair potential functions. Calculations are made with the inclusion of a long-range non-additivity term in the static lattice potential. It is found that when the experimental properties are satisfied this nonadditivity term becomes zero. The resulting pair potential parameters are then shown to give “best” reduction parameter values for Ar, Kr, and Xe, which allow the second virial and viscosity, two-body, gas-phase properties to be reduced to a pattern of corresponding-states behavior.
