Abstract
The structures and melting behavior of hard-core Yukawa clusters from N=2 to N=27 particles were investigated by Monte Carlo simulations for several ranges of the attractive Yukawa tail. In contrast to Lennard- Jones clusters, the ground state configurations of hard-core Yukawa cl usters with N > 13 are of either hcp or fee type, rather than icosahed ral. The shortest tail range allowing a liquid phase in the cluster sy stem is significantly longer than for bulk matter.
