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, Au^Z+_N → Au^Z+_N-1 + Au, for the larger and fission into a charged trimer plus the remaining cluster, Au^Z+_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, Au^Z+_N → Au^Z+_N-2 + Au₂, and of extremely asymmetric fission of the form Au^Z+_N → Au^(Z-1)+_N-1 + Au⁺.
