Model calculations for alkali halide clusters

Abstract
Model calculations of the total energy of alkali halide clusters using a rigid‐ion potential and a polarizable‐ion potential are presented. The calculations were carried out for four different materials for clusters having the composition (MX) n and M(MX)+ n , n=1–18. It turns out that for a cluster of a given size the configuration of lowest energy is usually model and material dependent. Certain configurations of especially low total energy are discussed in detail.
