Analytical static structure factors for the restricted primitive model

Méndez-Maldonado, G.A.; Ruiz-Estrada, H.; … - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 4, pp. 1759-1769

The mean static structure for the restricted primitive model formed by m ionic species is presented. Explicit expressions for the partial static structure factors are obtained from the Blum’s solution for the primitive model, which depend on an accumulative parameter, γ, expressed in terms of...
