Analytical static structure factors for the restricted primitive model

Abstract

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 the Debye length. Additionally, the number–number, number–charge and charge–charge structure factors are provided. An equation to calculate the radial distribution functions which tends to the contact values when r→σ+ is also given. Finally, molecular dynamics simulation is performed to assess the accuracy of the theoretical results.
