摘要：

The absorption and emission bands from calcium, strontium and barium atoms produced in superfluid helium have been observed. A model calculation on the basis of the bubble model is reported, which can describe the main observed features such as line shifts and broadenings. From a comparison with the experiment we conclude that the investigated atoms form a bubble state in the liquid similar to the system of barium ions and excess electrons. © 1990.
