| Abstract: | Exact semi-analytical expressions are obtained for the zero density site-site distribution function and the second virial coefficient for homonuclear square-well diatomics. The diatomic molecules considered here are composed of two fused square-well spheres with hard core diameter σ, well diameter λσ, and dimer bond length L, such that 0<Lˇ-σ and 1ˇ-λˇ-1+L/σ. Very accurate, although approximate, analytical expressions are also given for these functions. |
