Abstract
Level differences between two baths of liquid helium connected by an orifice are generated by a charged vortex-ring beam incident on a diaphragm containing the orifice. The data are interpreted in light of phase slippage caused by vortex rings which overlap the orifice. The effects of vortex-ring interactions are discussed.Keywords
