Cluster ions of aluminum, gallium, and indium are produced by the sputtering of pure metal targets. The cluster ion abundance distributions are found to parallel those reported for sputtered Al cluster ions. Investigations of the unimolecular dissociation behavior indicate similar patterns of stability among the cluster ions of these three elements. Anomalous stability is observed for those species having electronic structures that correspond to the closing of electronic shells predicted by the spherical jellium model. Unimolecular dissociation product branching data indicate relative ionization energy trends.

The mass distributions of ahnninum negative cluster ions and their binary cluster ions mixed with a carbon atom, generated by laser vaporization, were measured. In the range from n= 5 to 70, the mass distribution of pure aluminum negative cluster ions, Al;, exhibits one peak at n= 13 and one step be
