摘要：

We report the first measurements of the electronic absorption spectrum of a metal cluster under collision-free gas-phase conditions. Na3 molecules were produced in a supersonic molecular beam and mass-selective absorption spectroscopy was performed in the visible wavelength region (405-690 nm) by two-photon ionization together with mass-spectrometric detection. Two band systems were found at 625 and 670 nm. The experimental results are compared with recent theoretical calculations. © 1979.
