ELECTRON-ATTACHMENT TO METALLIC CLUSTERS

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