- Abstract
It is demonstrated how by selection of pre-precursor cluster ions Ag(2n-1)/2+ and collision-induced dissociation an ensemble of Ag(2n)/2+ can be produced, which is not contaminated by Ag(n)/+ clusters of the same size-to-charge state ratio, n/z. By use of this technique, Ag16/2+ and Ag18/2+ precursor ensembles have been prepared for further investigations. They are observed to decay by neutral monomer evaporation, Ag(2n)/2+→ Ag(2n-1)/2+ + Ag, and trimer fission, Ag(2n)/2+ → Ag(2n-3)/+ + Ag3/+, and show no sign of symmetric fission.
