 note = {AA00773679, We present evidence for a nonzero pressure, T ­ 0 superfluid phase transition of 3He in 98.2% open aerogel. Unlike bulk 3He which is a superfluid at T ­ 0 at all pressures (densities) between zero and the melting pressure, 3He in aerogel is not superfluid unless the 3He density exceeds a critical value rc. About 90% of the 3He added above rc contributes to the superfluid density. [S0031-9007(97)03585-0], 金沢大学理学部},
