Abstract: The structure and energetics ofPdN(N = 5–80)clusters have been studied extensively by a Monte Carlo method based on Sutton–Chen many-body potential. The basin-hopping algorithm is used to find the low-energy minima on the potential energy surface for each nuclearity. A variety of structure types (icosahedral, decahedral and fcc closed-packed) are observed forPdclusters. Some of the icosahedral global minima do not have a central atom. The resulting structures have been compared with the previous theoretical results.
