Abstract

In this paper, by considering Lenard-Jones potential between disc-shape molecules, the radial distribution function, the direct correlation function and the structure factor are calculated by using compressibility and Ornstein-Zernike equations. In addition, the pressure and compressibility equations for this potential are calculated. Results show that for the L. J. potential, the radial distribution function does not approach zero in molecule's diameter range.
