A heuristic approach for the densest packing fraction of hard-sphere mixtures (Q2685092)

In a previous work [``Structural and thermodynamic properties of hard-sphere fluids'', J. Chem. Phys. 153, No. 12, Article ID 120901, 30 p. (2020; \url{doi:10.1063/5.0023903})], the authors proposed a simple approach to derive the jamming packing fraction of a hard-sphere mixture from the knowledge of the random close-packing fraction of the monocomponent system. In this paper an extension of that approach is applied to provide an approximate formula for the densest packing fraction of a given hard-sphere mixture in terms of the face-centered cubic (fcc) close-packing fraction of a monocomponent hard-sphere system.
