### Abstract

We investigate the properties of binary mixtures of hard-sphere fluids with nonadditive diameters: calling R_{ij}- the distance of closest approach between particles of species i and j we assume R_{12}=1/2(R _{11}+R_{22})+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(R_{22}-R _{11}), in one dimension. For the three-dimensional case the Percus-Yevick equation is solved partially.
