Abstract
Results showing the attenuation of second sound due to the flow of He II film from a beaker into a resonant cavity are presented. The attenuation caused by the film flow is found to depend on the height above the cavity of the bulk He II level in the beaker. These results are interpreted in terms of vortices which are carried by the film into the resonant cavity.Keywords
