Following the assumption of the mean spherical approximation, analytical expressions of the first-order radial distribution function are obtained 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.
