Yp. Tang et Bcy. Lu, FIRST-ORDER RADIAL-DISTRIBUTION FUNCTIONS BASED ON THE MEAN SPHERICALAPPROXIMATION FOR SQUARE-WELL, LENNARD-JONES, AND KIHARA FLUIDS, The Journal of chemical physics, 100(4), 1994, pp. 3079-3084
Following the assumption of the mean spherical approximation, analytic
al expressions of the first-order radial distribution function are obt
ained for the square-well, Lennard-Jones, and Kihara potentials with a
hard core through a complex-plane analysis. The developed expression
yields good agreement with the available computer simulation data for
the radial distribution function of the Lennard-Jones fluid.
