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 clusters with N>13 are of either hcp or fcc type, rather than icosahedral. The shortest tail range allowing a liquid phase in the cluster system is significantly longer than for bulk matter. © 1996 The American Physical Society.Keywords
