✦ Synopsis

The optical absorption of small mass selected Ag. clusters (n = 57, 9, 11) embedded in solid Ar has been measured. Strong absorption has been found between 3 and 4.5 eV. The absorption spectra show l-3 major peaks depending on the cluster size. The width of these peaks is considerably smaller than commonly found in gas phase photodepletion experiments. A simple model based on a Drude metal, and neglecting the dielectric constant of the surrounding medium, gives satisfactory agreement with experiment.

The mean resonance energy (do> =R.fwwa(o) do/\_fu(o) dw calculated from the optical absorption spectra ofAg, in solid Ar shows strong variations as a function of cluster size, giving maxima at n =8,18 and 34. This behavior is discussed in terms of the electronic shell model. Static dipole polarizabi
