Investigation of surface plasma resonances in small sodium clusters

  • Photoabsorption cross sections of small neutral sodium clusters are measured at wavelengths from 452 to 604 nm. We find that surface plasma oscillations of the valence electrons dominate the photoabsorption spectra. The experimental results are consistent with predictions based on an extended Clemenger-Nilsson model, general sum rules, and the experimental static electric polarizabilities. For Na8 a single broad resonance is observed, the peak wavelength is in excellent agreement with the model.Photoabsorption cross sections of small neutral sodium clusters are measured at wavelengths from 452 to 604 nm.
