Second-Sound Velocity, Gravitational Effects, Relaxation Times, and Superfluid Density Near the Tricritical Point in 3He-4He Mixtures

Abstract

There has been considerable interest recently in the behavior of liquid 3He-4He mixtures near the tricritical point. We wish to report results for the second-sound velocity1 in this system which yielded information about the superfluid density, the coherence length, the phase diagram, the effect of gravity, and concentration relaxation times
