Nucleation in supersaturated solutions of He3 in He4 at negative pressures
Depending on the He3 concentration, thermal nucleation in -43He supersaturated liquid mixtures at negative pressures may be originated either by bubble or by rich3 drop formation. We have investigated this phenomenon within a density-functional approach, determining the regions in the pressure 3He-c...

| Sumario: | Depending on the He3 concentration, thermal nucleation in -43He supersaturated liquid mixtures at negative pressures may be originated either by bubble or by rich3 drop formation. We have investigated this phenomenon within a density-functional approach, determining the regions in the pressure 3He-concentration plane where bubbles or drops likely drive the nucleation process. As an illustrative example, we also give the homogeneous nucleation pressure corresponding to 50 and 100 mK temperature. © 1995 The American Physical Society. |
