Zusammenfassung

The decay mechanism of excited electronic states in small Ag nanoclusters is studied using time-resolved photoelectron spectroscopy. The low density of states in these clusters inhibits Auger-like decay channels that are responsible for ultrafast relaxation of optically excited states in bulk Ag. Thus, much longer relaxation times are expected for small clusters showing large gaps between electronic states. In contrast to this expectation, lifetimes below 1 ps were observed for most of the Ag - n (n
