Number of Single, Double, and Triple Clusters in a System Containing Two Types of Atoms Available to Purchase

A set of graphs are presented from which one can read directly the probability that, in a lattice containing two types of atoms A and B randomly distributed over the lattice sites, a type A atom will be in a cluster of one, two, or three A atoms. Results are presented as a function of concentration for simple cubic, body‐centered cubic, face‐centered cubic, and hexagonal close‐packed lattices.
