Abstract:
The emission of photons in the visible wavelength range from mass-selected Ag+ n, Cu+ n, Pt+ n and Pd+ n () clusters is observed. Photons are detected 10-4 s after the cluster generation in a sputter source. The emission intensities display distinct variations with cluster size and material. The observations are interpreted in terms of the decay of metastable states which are excited during the high-energy sputtering process used for the generation of these clusters.
