Abstract
The absorption and emission spectra of two-valence-electron atoms in s uperfluid helium (He II) are studied systematically using pulsed dye l asers. Isolated atoms are dispersed in He II by laser ablation. Change s in the bubble size by electronic excitation are determined from the measured spectra. Molecular and cluster lines are identified.
