Abstract
The rate at which negative ions nucleate charged vortex rings in isotopically pure superfluid helium-4 has been measured for electric fields of up to 2.5× V with pressures and temperatures within bars, K. It is found that the nucleation process is completely quenched () for V . The implications of this result for theories of the nucleation mechanism are discussed.
