Structure and Cohesive Energy of Cu Clusters （Ⅰ）——Application of Embedded Atom Method to Study of Metal Clusters

Based on the Embedded-Atom Method, we have performed a semiempirical calculation of structure and cohesive energy for （Cu）_n （n=2,4,6-8,12,13） clusters. The results are in fairly good agreement with those calculated with ab initio methods. The cohesive energy is found to increase with the increasing number of average neighbour atoms.
