Abstract
The size dependent evolution of the electronic structure of isolated gas-ph ase rhenium clusters Re-n (n = 2-40) is measured by photoelectron (PE) spec troscopy at 4.99 and 6.42 eV photon energies. For very small clusters the p hotodetachment threshold energies show a strong size dependence varying bet ween 1.6 eV (Re-2) and 2.6 eV (Re-13). As for larger clusters, electron aff inities (EA) increase smoothly toward bulk work function (WF). Bulk-like el ectronic features can already be observed around very small cluster sizes.
