摘要：

The embedded atom method (EAM) was used to determine the equilibrium shapes of small platinum and palladium clusters (N=5-60 atoms). The stability of various polyhedral symmetries was performed at OK. A search for the presence of any other lower energy structures was also carried out. Pt clusters reconstructed to lower energy clusters even at the magic numbers. Pd also reconstructed to lower energy structures except at the magic number sizes where the icosahedron was found to be the most stable.
