Abstract

A detailed investigation of vortex nucleation in He II containing traces of He3 isotopic impurity is reported. Systematic measurements of the nucleation rate due to negative ions were made at 23 bars. A model is proposed which, when fitted to the data, implies that a single He3 atom trapped on the surface of the ion has the dual effect of reducing the critical velocity for vortex nucleation by circa 4 m s1, while simultaneously increasing the corresponding rate constant by a factor of circa 103.
