Abstract
Second electron affinities of and clusters and the dissociation energies for fission of the and dianions are calculated using the finite-temperature shell-correction method and allowing for triaxial deformations. Dianionic clusters with 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 with appearance sizes and
