Abstract
We describe a new optical interferometric technique which we have applied to 3He-4He liquid mixtures in the phase separation region. The formation and slow propagation of a concentration front is observed when the phase separation equilibrium is disturbed by sudden heating. The phenomenon is analyzed in terms of a concentration-dependent diffusion constant, and the results indicate critical behavior of the diffusion constant on the normal side of the lambda line. The application of the optical method to studies of interphase surface tension and crystallization is also indicated.
