Abstract

The investigation of silver clusters prepared by the gas-aggregation technique or laser vaporization using mass and fluorescence spectroscopy provides some new information about the influence of the experimental parameters for the cluster size distribution.¹ The observation of time-resolved emission spectra in the case of laser vaporization allows us to distinguish between different size species. This, together with mass spectroscopy and fluorescence spectroscopy, using the gas aggregation technique is useful for better understanding of how the cluster grows dynamics. The questions of fragmentation, double ionization, and Coulomb explosion are discussed as well as the influence of charged particles for the resulting size distribution. In addition to the investigations on naked metal clusters some results on molecules adsorbed on clusters are reported.²
