Abstract:
We have investigated the phase separation in supersaturated -43He liquid mixtures due to nucleation via thermal fluctuations below ∼200 mK and found a large discrepancy in the supersaturation value between recent experiments (∼1%) and nucleation theory (∼10%). We suggest that the rather small degree of supersaturation found experimentally is due to destabilizaiton of vortices with cores rich in He3. © 1995 The American Physical Society.

- The value obtained in, Ref. 4, is σ sim 0.018 K AA-2, well within the experimental error bars; We have computed partial(Δ μ3)/ partial x midxs from Fig. 4 of, Ref. 3, obtaining 2.3 K instead of the value quoted in, Ref. 5, (sim 0.3 K) which came also from the same reference. In our opinion, this gross error invalidates the numerical calculations of Lifshitz et al; Xiong, Q., Maris, H.J., (1989) J. Low Temp. Phys., 77, p. 347
