Abstract
A Penning trap has been applied to the study of photoinduced unimolecular dissociation of Ag10+. The cluster decays by the evaporation of a neutral atom. At photon energies of 1.75 eV and 1.59 eV lifetimes of 330 ± 70 μs and 11.1 ± 2.9 ms, respectively, have been measured. By the use of statistical models the dissociation energy is determined from the observed lifetimes and their corresponding exaltation energies. The values from both measurements agree, indicating the reliability of free cluster decay studies at lifetimes in the-10 ms range. This development may open new possibilities, e.g. the investigation of isomeric states and of radiative cooling.
