Electron attachment to metallic clusters

New calculations of the low-energy electron attachment cross section to metallic clusters are reported. We include all the bound states of the negative ion as possible final states for attachment and calculate the electron attachment cross section, which results in more spectra structure than previously reported. The calculations are more refined than earlier work, in that they no longer depend on experimental optical cross section data. Instead, an RPAE calculation of the collective resonance in the cluster is performed.
