A solution of the Born-Green equation for the radial distribution function may be found as a series in ascending powers of the density. This method is applied to a fluid of rigid spherical molecules, and the results are compared with those which Kirkwood, Maun & Alder obtained by means of numerical integration. For such molecules it is possible to show that the close-range structure at a distance between n and n + 1 diameters from a central molecule is of the order of the density raised to the n th power ( n integral). When the Lennard-Jones potential function is employed, the first and second approximations to the radial distribution function thus obtained are shown to be identical with those resulting from a rigorous development of this function in powers of the density.
