Cy. Cha et al., TEST OF THE JELLIUM MODEL - PHOTOELECTRON-SPECTRA OF SMALL COPPER CLUSTERS, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 26(1-4), 1993, pp. 307-309
Copper cluster anions in the size range of 1-18 atoms are studied by p
hotoelectron spectroscopy. Using photons of 5.0 eV energy the electron
ic level structure built from the delocalized s-orbitals of the atoms
is revealed. An attempt is made to assign the observed bands to the el
ectronic shells predicted by the jellium model. Even though the genera
l behavior resembles the predictions of this model, the spectra are mu
ch more complicated reflecting the discrete atomic geometry of these p
articles.
