Mutual diffusion in 3He-4He solutions near the critical vaporization line
Efremova R. I., Matizen E. V.
It is shown experimentally that the regular component of the mobility is larger than the singular component in the range of solutions studied. As a result, the thermodiiFusion ratio and the thermal conductivity exhibit a special behavior with indices φ =1.2 and ψ = 0.63, respectively.
