Abstract
The embedded atom method (EAM) was used to determine the equilibrium s hapes of small platinum and palladium clusters (N=5-60 atoms). The sta bility 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 m agic numbers. Pd also reconstructed to lower energy structures except at the magic number sizes where the icosahedron was found to be the mo st stable.
