N2 - We have confirmed earlier suspicions that the rate nu at which negative ions nucleate vortex rings in Hell is quite extraordinarily sensitive to the presence of tiny traces of 3He isotopic impurity. We find that, in low electric fields E, nu(E) for natural helium exhibits a maximum whose position and magnitude are dependent on temperature.
