Morse Clusters

The Morse potential has a single variable parameter that determines the range of the potential. This parameter gives Morse clusters a much greater variety of structural behaviour than Lennard-Jones clusters.

Depending on the range of the potential the clusters can be icosahedral, decahedral, close-packed (fcc, hcp or some mixture) or even polytetrahedral (involving defects called disclination lines). Because of this diversity Morse clusters provide:
