Second virial-coefficient of the D-dimensional hard Gaussian overlap model Cuesta, J. A. Fernández Tejero, Carlos 536 Isotropic-nematic transition Of-revolution fluid Molecular theory ellipsoids Termodinámica 2213 Termodinámica © 1991 Elsevier Science Publishers B.V. This work has been supported by a grant from the Dirección General de Investigación Científica y Técnica (Spain) under no. PB88-0140. We thank M. 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.
