Abstract

The low-energy dissociation channels of mass selected silver cluster ions Agn2+ (n = 9 - 24) are determined by collision induced dissociation (CID) in a Penning trap. While all clusters of the size n ≥ 17 evaporate neutral monomers, most smaller clusters undergo asymmetric fission of the form Agn2+ → Agn-3+ + Ag3+. However, Ag152+ and Ag112+ emit monomers which indicates shell or odd-even effects. The observed fragmentation pathways are different from previous reports of measurements with sputtered Agn2+.
