Abstract
Antimony clusters are produced by the inert gas condensation technique. They are found to be built from Sb4 units. The fragmentation by evaporation of Sb4 units is studied as a function of the excess energy in the cluster. By this way the binding energy of the Sb4 units in the cluster is found to be about 1.5 eV, well below the binding energy of a Sb atom in the bulk and in Sb4(≃3eV). The evolution of ionization potentials of Sb4n clusters confirms that their structure is probably non metallic. Finally the possible metastable character of this Sb4n structure is discussed.
