    "abstract": "The time-dependent local density approximation is applied to the optical\nresponse of the silver clusters, Ag_2, Ag_3, Ag_8 and Ag_9^+. The calculation\nincludes all the electrons beyond the closed-shell Ag^{+11} ionic core, thus\nincluding for the first time explicitly the filled d-shell in the response. The\nexcitation energy of the strong surface plasmon near 4 eV agrees well with\nexperiment. The theoretical transition strength is quenched by a factor of 4\nwith respect to the pure s-electron sum rule in Ag_8 due to the d-electrons. A\ncomparable amount of strength lies in complex states below 6 eV excitation. The\ntotal below 6 eV, about 50% of the s sum rule, is consistent with published\nexperiments.",
