Abstract

ONE of the most striking features of the film flow in liquid helium II is provided by the fact that the rate of transfer seems to be largely independent of the experimental conditions1. It was thought for some time that the rate was influenced by the geometrical shape of the transfer vessel, or by a temperature gradient in the film2, or by small amounts of thermal radiation3. However, recent experiments by R. Bowers and one of us4 have demonstrated that the real cause for these changes in the transfer-rate was a contamination of the solid surface over which the transfer took place with a thin layer of solid air. It was also found that contamination with solid hydrogen and solid neon produced similar effects.
