摘要：

We report the observation of electronically excited states of Li4, using depletion spectroscopy. The obtained spectra reveal five electronic bands between 380 and 760 nm. Energetic locations and absorption cross sections (ranging from 0.3 to 4 2) fully agree with previous molecular configuration-interaction ab initio calculations. Vibronic structures are also observed; they look promising for development of accessibility to adiabatic surfaces and equilibrium geometries in metallic tetramers. © 1990 The American Physical Society.
