Abstract
Torsional oscillator measurements of 3He-4 He mixtures in 95% porous aerogel found a phase diagram similar to that in 98% porous aerogel. The coexistence boundary on the 3He rich side resides very close to, but nevertherless is detached from the superfluid transition line. Together with the findings in 98%, 87%, and 99.5% porous aerogel, this result supports the interpretation that the phase separation of 3He-4 He mixture in aerogel is induced by the capillary condensation of 4He films from neighboring silica strands into 4He rich domains.
