Ring Vortex Destabilization in Supersaturated 3He-4He Liquid Mixtures at Low Temperatures

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 3He at smaller values of the concentration than small ring vortices. Our c...
