Baus for useful suggestions.Exact analytical expressions for the excluded volume and the second virial coefficient of the D-dimensional hard Gaussian overlap model are obtained. The functional form of the excluded volume is proven to be independent of D provided D greater-than-or-equal-to 2. The second virial coefficient is given in terms of a hypergeometric function but alternative formulas for some particular values of D are also reported.engjournal articlehttp://dx.doi.org/10.1016/0375-9601(91)90620-Nhttp://www.sciencedirect.com/restricted access536Isotropic-nematic transitionOf-revolution fluidMolecular theoryellipsoidsTermodinámica2213 Termodinámica
