Abstract. We studied the electronic structure of quasi size-selected silver clusters grown in nanopits of a graphite surface using ultraviolet photoelectron spectroscopy at T=40 K. For clusters with more than 9×102 atoms the initial state of the d-electrons has already reached the bulk limit, but there is a dynamic final-state effect which we can explain with a simple model taking into account the finite lifetime of the photohole (corresponding to a charged cluster) and the cluster-substrate interaction on a femtosecond timescale. Below a critical cluster size of about 5×102 atoms we have observed additional initial-state effects.
