ChemInform Abstract
Charged antimony and bismuth oxide clusters are generated in a pulsed arc cluster ion source or a laser vaporization source and detected by time-of-flight mass spectrometric techniques. The oxide clusters show magic number behavior and contain the metal atoms in a formal +3 oxidation state. For Sb the formation of cluster oxides containing Sb+V becomes favoured, especially at higher oxygen concentrations. The observed magic cluster oxide patterns are most likely caused by the thermodynamical stability of the cluster.
