متن کاملElectrons in Superfluid Helium-4
We review the current status of theory and experiment concerning electrons in superfluid helium-4 with an emphasis on some of the unsolved problems. Although calculations of the bubble structure have been confirmed in detail by measurements of the optical absorption spectrum, the energy of interaction of a bubble with a vortex is not understood. We discuss the theory behind a proposed experimen...

متن کاملExperiments with single electrons in liquid helium
We have developed an apparatus which can be used to make movies showing the motion of individual electrons in liquid helium. A sound wave is used to explode an electron bubble for a fraction of a microsecond and to make it grow to have a radius of around 10 microns. While the bubble has this large size it is illuminated with a flash lamp and its position recorded. We report on a number of inter...
متن کاملFine structure of helium and light helium-like ions
Calculational results are presented for the fine-structure splitting of the 2P state of helium and helium-like ions with the nuclear charge Z up to 10. Theoretical predictions are in agreement with the latest experimental results for the helium fine-structure intervals as well as with the most of the experimental data available for light helium-like ions. Comparing the theoretical value of the ...
