| Abstract: | The Generalized Mean Spherical Approximation for a hard-sphere fluid developed by Waisman E. Waisman, Mol. Phys. 25, 45 (1973)] over forty years ago is revisited. The relatively recent C. F. Tejero and M. López de Haro, Mol. Phys. 105, 2999 (2007)] completely analytical results for the direct correlation function of such approximation are used to assess the simplification introduced by Henderson and Blum D. Henderson and L. Blum, Mol. Phys. 32, 1627 (1976)]. The conclusion is reached that such simplification is a rather valuable compromise between simplicity and accuracy. |
