Abstract
An experimental setup for photoelectron spectroscopy on mass selected cluster anions is described. The photoelectron spectra reveal the electronic structure of the particles as function of their size (mass). For clusters consisting of elements which are counted among the simple metals, i.e., the alkali's as well as Cu, Ag, and Au, the electronic structure is indicative of extended, delocalized states formed by the atomic s-electrons. This is the first indication of metallic behavior even though the particles containing up to 20 atoms clearly exhibit a bandgap in the electronic structure. Additionally, in cases where vibrational finestructure is observed in the photoelectron spectra, the measured vibrational quanta allow to deduce the particle geometry. This is especially helpful in studies of chemisorption phenomena on the clusters. Moreover, electron phonon coupling constants can be extracted from a high resolution spectrum of C60, which confirm the alkali doped fullerenes to be conventional BCS Type super-conductors.
