Shouldered hard sphere model for charged colloidal dispersions

Augousti, A.T. and Grimson, M.J. (1984) Shouldered hard sphere model for charged colloidal dispersions. Physics and Chemistry of Liquids: An International Journal, 14, pp. 53-58. ISSN (print) 0031-9104

Abstract

The experimentally determined structure factor for an aqueous dispersion of charged polystyrene spheres is analyzed in terms of a system of particles interacting through a shouldered hard sphere potential. The fit of the model system to the experimental data is sufficiently good that the fluid represents a suitable reference system for perturbation studies of the small-angle scattering.
