“…The four different curves represent four different ways of obtaining the MSK-parameters from dilute gas data B, # and ~/ [10,11,13]. Again it can be seen that not only the dilute gas data can be correlated and predicted essentially within their experimental uncertainties (shaded area), but also the third virial coefficient is predicted within experimental error (-200 cm 6 mo1-2 at the maximum) when two dilute gas properties, here B and #, are used to determine the potential parameters.…”

A new three parameter pair potential for argon is suggested. Its parameters are determined from fitting it to data of the second virial coefficient and the throttling coefficient. Excellent predictions are achieved for the viscosity. The third virial coefficient and liquid state data are obtained in very good agreement with experiment when the Axilrod-Zeller-forces are included with the strength coefficient determined from the pair potential parameters. The new potential, referred to as the MSK, is as suitable for the correlation of the thermophysical properties of argon as the complicated Barker-Fisher-Watts-potential. It is hoped, therefore, that it will prove to be a simple flexible potential function for other forms of isotropic interactions as well.
