Description
Collision-induced dissociation (CID) of cooled, mass selected aluminum cluster ions (Al+2/sub --/7) by xenon, has been studied over an energy range of 0--10 eV (center of mass). These experiments were carried out in a new apparatus which is described in detail. From the product branching ratios and cross section magnitudes we derive qualitative structural information about the cluster ions. The fragmentation thresholds are analyzed to yield dissociation energies, approximate ionization potentials, and further structural information about the cluster ions and their neutral counterparts. Cluster stabilities range from 0.85 +- 0.40 eV for Al+4 to 2.25 +- 0.70 eV for Al+7. The results provide a stringent test for recent calculations on Al2/sub --/6
