Velocity oscillations of a freely rotating vessel with Helium II
Tsakadze Dz.S. , Tsakadze S.Dzh.
Experiments with free rotation of vessels with helium-II show that the perturbations of the vortex lattice lead to oscillations of the rotation velocity. These data serve as a certain confirmation of the premise that Tkachenko oscillations of the vortex lattice play a role in the behavior of pulsars.
