Radial Distribution Functions and Superficial Quantities for Rigid Sphere Fluids; Method of “Point” Chemical Potential Using Scaled Particle Theory

The radial distribution of rigid spheres of diameter a about a single fixed solute rigid sphere of diameter b was calculated using the method of “point” chemical potential and effective local density, together with results from the scaled particle theory of rigid sphere fluids. This method, which avoids the superposition approximation, gives rise to a nonlinear integral equation which was solved numerically for various values of b in the interval a ≤ b
