Transport properties of spin polarized /sup 3/He-/sup 4/He mixtures

We have calculated the viscosity, thermal conductivity, and longitudinal spin diffusion coefficient in /sup 3/He-/sup 4/He mixtures which are spin polarized. The calculation applies to all temperature regimes. We have also calculated the Onsager cross coefficient which arises because of the coupling between heat and longitudinal spin currents. The interaction between /sup 3/He quasiparticles is taken to be a constant as a first approximation. We have also investigated the changes brought about by allowing the interaction to vary with the momentum of the quasiparticle.
