摘要：

An ab initio investigation shows that the deformed section of the fcc lattice for Na-20 with T(d) symmetry gives rise to three intense transitions with differing oscillator strengths due to excitations localized in different parts of the cluster. These predictions are in agreement with the experimental findings by two-photon femtosecond spectroscopy and the depletion technique. The study of different structures for Na-20 reveals that the spectroscopic patterns strongly depend on the position of the nuclei.
