The energy dependence of the total and the partial dissociation cross sections is measured, and the dissociation energies are estimated. Pronounced odd even alternations are found for the dissociation energies, as well as for the fragmentation pathways. Here we discuss the stability of the individual clusters, and the energy dependency of their partial cross sections for the individual processes.
