摘要：

The optical response of small potassium particles grown on an oxidized silicon substrate has been investigated by surface differential reflectivity spectroscopy. Together with the usual dipolar resonance, an additional resonance is observed in the spectra at larger energy. We assign the origin of this resonance to the multipolar coupling between the potassium particles and the substrate. This is demonstrated by the good agreement found between the experimental data and spectra calculated using a model where this multipolar coupling is included. [S0163-1829(99)11731-4].
