  - We report measurements of the photodestruction cross sections of small sputtered
    negatively charged silver clusters (AgN−, 5 ≤ N ≤ 19). Resonance-like peaks are
    observed in the optical spectra which can be attributed to collective electron
    excitations. In contrast to neutral and positively charged clusters, the resonance
    energies are far above the  electron emission threshold. With decreasing cluster
    size the resonance positions distinctly shift towards lower energies. This red-shift
    is explained by an extension of a semi-empirical model by Liebsch which we previously
    used to interpret the blue-shift in AgN+ [J. Tiggesbäumker, L. Köller, K.H. Meiwes-Broer
    and A. Liebsch, Phys. Rev. A 48 (1993) R1749], now including the polarizabilities
    of small metal clusters.@eng
