description

Using Penning-trap experiments and a shell-correction method incorporating ellipsoidal shape deformations, we investigate the formation and stability patterns of trianionic gold clusters. Theory and ex- periment are in remarkable agreement concerning appearance sizes and electronic shell eects. In contrast to multiply cationic clusters, decay of the trianionic gold clusters occurs primarily via electron autodetach- ment and tunneling through a Coulomb barrier, rather than via ssion.
