00925njm 22002777a 4500 dc Cuesta, J. A. author Fernández Tejero, Carlos author 1991 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. 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/ Second virial-coefficient of the D-dimensional hard Gaussian overlap model
