LIQUID-GAS TRANSITION FOR HARD-SPHERES WITH ATTRACTIVE YUKAWA TAIL INTERACTIONS

We describe the liquid-gas transition in the hard sphere system with Yukawa tail interactions in the mean spherical approximation. The dependence of critical temperature and density on the range of the interaction is shown and the spinodal curve for a short-ranged potential and a long-ranged potential is presented. The compressibility, energy and virial pressures are presented for a long-ranged potential. Liquid phase pressures are calculated by integrating round the coexistence region, rather than through it. © 1979.
