Hydrodynamic Theory of Fourth Sound in a Moving Superfluid — A Discussion of Size Effects

  • David J. Bergman


A previous discussion of fourth sound in a moving superfluid is extended to include a detailed estimate of size effects. Comparison with experiment still shows a considerable disagreement. This might indicate the existence of relaxation phenomena on a time scale of 10−2 –102 sec. which have not yet been observed.
