DISSOCIATION OF Au-n (n=3,4) MICROCLUSTERS: A MOLECULAR DYNAMICS SIMULATION

The dissociation of Au-3 and Au-4 microclusters has been investigated using a molecular-dynamics computer simulation. The potential energy function used in the calculations includes two-and three-body interactions, which are represented by Lennard-Jones and Axilrod-Teller potentials, respectively. It has been found that dissociation starts for both clusters after 3000K.
