Second virial-coefficient of the D-dimensional hard Gaussian overlap model Cuesta, J. A. Fernández Tejero, Carlos © 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. 2023-06-20T18:54:14Z 2023-06-20T18:54:14Z 1991 journal article 0375-9601 10.1016/0375-9601(91)90620-N https://hdl.handle.net/20.500.14352/58895 http://dx.doi.org/10.1016/0375-9601(91)90620-N http://www.sciencedirect.com/ eng PB88-0140 restricted access Elsevier
