Energy-resolved collision induced dissociation of Cun+ (n=3D2-9) with Xe is
presented from ~0.1eV to above 15eV (center of mass). 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.
