(1987) Evidence for an energy barrier impeding the creation of quantized vortices in He II. Japanese Journal of Applied Physics, 26 (Supple). pp. 73-74.

The rate nu at which negative ions create quantized vortex rings in isotopically pure He II has been measured for temperatures 70 < T < 500 mK, pressures 12 < P < 19 bar and electric fields 10^4 < E < 10^S V/m. The result can be taken to imply the existence of an energy barrier impeding the nucleation process of ~3K.
