Abstract
A two component mixture of hard spheres manifests, in the fluid region of the phase diagram, a nonmonotonic trend towards ordering when the two-species diameter ratio is gradually reduced (see: G. Giunta, M. C. Abramo, and C. Caccamo, 1985, Molec. Phys., 56, 319). This behaviour can be explained in terms of simple geometrical considerations and appears as an imprint of the close-packing configuration.
