Editorial: JOURNAL OF CHEMICAL PHYSICS, 121(22), p.11232-1123, 2004.


For a nearest-neighbor Ising model on a square lattice all cluster configurations with 17 or fewer spins are identified. In neglect of cluster-cluster interactions, critical sizes and barriers to nucleation are obtained as functions of temperature and magnetic field for two alternative definitions of a „critical cluster.”
