Experimental Values

The radial distribution function and thermodynamic properties of argon are calculated using the (12, 6) potential and the Percus–Yevick approximation. The results are compared with experimental values for argon, the machine calculations of Verlet and of McDonald and Singer, and with the perturbation theory of Barker and Henderson.

Triangular Well Potential

Accurate calculations of the second order term in the free energy and the first order term in the radial distribution function in the Barker–Henderson (BH) perturbation theory are presented for the triangular well potential. The BH theory is found to be fully satisfactory for this system. Thus, the conclusions of Card and Walkley regarding the accuracy of the BH theory are erroneous.
