Abstract

We investigate the properties of binary mixtures of hard-sphere fluids with nonadditive diameters: calling Rij- the distance of closest approach between particles of species i and j we assume R12=1/2(R 11+R22)+α with α≠0. We find the exact correlation functions as well as the solution of the Percus-Yevick integral equation for this system with 0≤α<1/2(R22-R 11), in one dimension. For the three-dimensional case the Percus-Yevick equation is solved partially.
