Vortex Fluctuation Contribution to the Negative Ion Trapping Lifetime
In the early work of Donnelly and Roberts1 on the trapping of negative ions by vortex lines in He II (bubble radius R, vortex circulation κ = h/m, and core parameter a) it was noted in passing that the trapping lifetime did not exhibit quite the right temperature dependence required by experiment.
