Abstract
Collision induced dissociation is applied to study the fragmentation channels of multiply charged gold clusters, Au2+N, size N = 7-35, and Au3+N, N = 19-35, stored in an ion cyclotron resonance (Penning) trap. The main dissociation pathways are neutral monomer evaporation, AuZ+N → AuZ+N-1 + Au, for the larger and fission into a charged trimer plus the remaining cluster, AuZ+N → Au(Z-1)+N-3 + Au+3, for the smaller clusters. In the intermediate cluster size region an odd-even alternation of the two competing decay pathways is observed. In addition, for some specific cluster sizes there are indications of neutral dimer evaporation, AuZ+N → AuZ+N-2 + Au2, and of extremely asymmetric fission of the form AuZ+N → Au(Z-1)+N-1 + Au+.
