“…For macroscopic crystals the shape of the spectrum has been shown to be independent of the photoelectron ejection-direction. 17 This justifies our comparison between the spectra of solid-state crystals and the clusters of our experiments, which can be considered as polycrystals, randomly oriented in space.…”

“…17 The onset of the cluster valence band (corresponding to the cluster work function) has been detected at ∼4.1 eV binding energy, which can be compared to the work function of ∼4.3 eV of solid polycrystalline aluminum. 18,19 The lower work function implies the presence of initially negatively charged clusters, as expected because of the high sputtering powers used in the magnetron cluster source.…”

The electronic structure of free aluminum clusters with ∼3-4 nm radius has been investigated using synchrotron radiation-based photoelectron and Auger electron spectroscopy. A beam of free clusters has been produced using a gas-aggregation source. The 2p core level and the valence band have been probed. Photoelectron energy-loss features corresponding to both bulk and surface plasmon excitation following photoionization of the 2p level have been observed, and the excitation energies have been derived. In contrast to some expectations, the loss features have been detected at energies very close to those of the macroscopic solid. The results are discussed from the point of view of metallic properties in nanoparticles with a finite number of constituent atoms.

“…Although initially calculations based upon this approach were also found to qualitatively predict the spectral changes observed in the higher energy regime [37,38], subsequent experimental studies indicated that at these energies a rather complete averaging out over reciprocal space occurs [39,40]. The observation of strong direct transition effects in the low and intermediate energy range, and the full zone averaging that takes place for hν ≈ 10 3 eV, was first explained by Shevchik [41][42][43].…”

XPS valence band spectra reflect the electronic density of states weighted with cross-sections. The spectra will give additional information about the symmetry of the electron wave function, if they are measured in dependence on the electron emission angles. VaIence band spectra of SnS, SnSe, SnTe, and SnS, are measured partly in dependence on the polar angle 8. These measurements allow an identification of the symmetry of valence orbitals from intensity variations of the valence band maxima.XPS-Valenzbandspektren bilden die mit Wirkungsquerschnitten gewichtete elektronische Zustandsdichte ah. Werden die Spektren in Abhangigkeit von den Elektronenemissionswinkeln aufgenommen, so liefern sie zusatzliche Informationen iiber die Symmetrie der Elektronenwellenfunktion. Von SnS, SnSe, SnTe und SnS, werdenteils in Abhangigkeit vom Polarwinkel 8die Valenzbandspektren gemessen. Diese Messungen ermoglichen es, die Symmetrie der Valenzorbitale aus Intensit~ts~inderungen der Valenzhandmaxima zu hestimmen.
