Abstract

The compressibility factors and configuration energies of the Lennard-Jones pair-additive fluid were calculated in terms of the PY, HNC, HTA, ORPA, and EXP approximations, the Lado method and the method by Madden and Fitts. The results were compared with Monte Carlo data. In the gaseous region, the EXP approximation, the Lado method and the method by Madden and Fitts are substantially better than the remaining approaches. The last-mentioned method is the most successful.
