Abstract
Using picosecond pump&probe technique followed by mass-selective detection, the dynamics of excited states of cold Nan=3...8-clusters in a supersonic beam — excited at λ=422nm — have been studied in time-resolved two-photon-ionization (TPI)-experiments. With growing cluster size a monotonous decrease of the decay times is observed except in the case of Na7 known to be a very symmetric cluster.
