(E,2E) SPECTROSCOPY OF ATOMIC CLUSTERS

The potential of applying (e, 2e) spectroscopy to metallic clusters is discussed within the jellium model. it is shown that such experiments would allow the investigation of the analogy between cluster and nucl ear structure. Distinct diffractive patterns in the state-selected tri ply differential ionization cross section as well as in the elastic ch annel reflect the effective cluster radius. Differences between the tr iply differential cross section for atomic systems and those for jelli um spheres are expected even if the valence electron states are not en ergetically resolved.
