Structure and energetics of Ni, Ag, and Au nanoclusters

The geometries and binding energies of the most stable isomers of nickel, silver, and gold nanoclusters ofze 6, 7, 12, 13, 14, 19, 38, 55, and 75 atoms, predicted with an n-body Gupta potential, are presented. Anxhaustive search for low-energy minima on the potential energy surface was carried out using an evolutivegenetic-symbiotic! algorithm. Our results confirm the ex..
