Radial Distribution Functions from a Linear Integral Equation

摘要

A linear integral equation derived by Mayer for the radial distribution function of fluids has been investigated numerically. To compare with other recent investigations of integral equations, a Lennardhyphen;Jones 6ndash;12 potential was used and the 55deg;C isotherm of argon investigated. Results for the pressure and the radial distribution function are less satisfactory than are obtained with other integral equations. An estimate of the validity of Kirkwood's superposition approximation in the range of the calculation was also made.
