We have carried out a detailed study of the frequency and damping of the oscillations in levels of two reservoirs of HeII which are coupled only via the mobile superfluid film. Our experiments cover the temperature range 1.
This thesis deals mainly with soraa investigations on the helium II film in motion. Som...
