This Letter describes the physical behavior of superfluid dispersions created by pressure quenching /sup 3/He-/sup 4/He mixtures into the miscibility gap. The two types of dispersions, namely, superfluid droplets within a normal-fluid continuous phase and the inverse, evolve differently. Under certain conditions near the tricritical point, light scattering during the early stages of separation displays a halo at a time-dependent wave k/sub m/proportionalt/sup -phi/, where phi shows a crossover from slow (phiapprox. =1/3) to fast (phi=1) growth within 0.1 s.
