Ring vortex destabilization in supersaturated He-3-He-4 liquid mixtures at low temperatures

Abstract : The effect of ring vortices on the destabilization of supersaturated liquid helium mixtures at very low temperatures is investigated as a function of pressure. We have found that large ring vortices trigger the segregation of He-3 at smaller values of rite concentration than small ring vortices. Our calculations indicate that the existence of ring vortices in the mixture is a possible mechanism to understand the rather small degree of critical supersaturation found in the experiments.
