摘要：
The absorption and emission spectra of two-valence-electron atoms in superfluid helium (He II) are studied systematically using pulsed dye lasers. Isolated atoms are dispersed in He II by laser ablation. Changes in the bubble size by electronic excitation are determined from the measured spectra. Molecular and cluster lines are identified.
