Magic numbers of alkali halide clusters.
01 January 1986
Recent experiments have shown that the most stable sodium halide NaX neutral and ionic clusters are cube shaped, but that the most stable CsI clusters may be either cube-shaped (high ionization energies) or have some other structure (low ionization energies). This other structure is identified here from its observed set of magic numbers in the context of a physical model which distinguishes CsI from NaX.
