Polydispersity Effects in Structural Properties of Binary-Species Percus-Yevick Fluid of Colloidal Hard Spheres

Abstract

Calculations are presented of the measurable structure factor of a binary-species polydisperse Percus-Yevick fluid of colloidal hard spheres with Schulz distributed diameters in order to discuss dependences of structural properties on the polydispersity and the multiplicity of species. On spatial density distributions of materials inside spheres, two cases are considered: homogeneous type spheres and Gaussian type spheres.
