摘要：

We report on the first laser spectroscopy of alkali atoms (Cs and Rb) and molecules (Na2 and Li2) in superfluid helium. General features of the observed spectra can be explained in terms of the spherical atomic bubble model. The excitation and emission spectra for the D2 lines, however, have double peaked profiles, indicating the importance of the nonspherical density distribution of surrounding helium atoms. The emission spectra for the molecules show well-resolved vibrational structures in the electronic ground states.
