Description
Second electron affinities of AuN and AgN clusters and the dissociation energies for fission of the AuN2- and AgN2- dianions are calculated using the finite-temperature shell-correction method and allowing for triaxial deformations. Dianionic clusters with N>2 are found to be energetically stable against fission, leaving electron autodetachment as the dominant decay process. The second electron affinities exhibit pronounced shell effects in excellent agreement with measured abundance spectra for AuN2- (N<30), with appearance sizes na2-(Au)=12 and na2-(Ag)=24.
