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.
