FERMI-LIQUID TRANSPORT COEFFICIENTS OF DILUTE SOLUTIONS OF HE3 IN HE4 AN ADDENDUM

Using recent exact solutions of the quasiparticle transport equation, we have reexamined the consistency between Bardeen, Baym, and Pines's phenomenological theory of dilute solutions of He3 in He4 and measurements of the spin-diffusion and thermal-conductivity coefficients of two solutions in the degenerate Fermi-liquid regime. Previously, Baym and the author had used lowest-order variational solutions for this purpose. Discrepancies of 10-15% persist which, beyond experimental uncertainty, must be attributed to oversimplification in treating the He3 scattering amplitudes as being independent of spin, velocity, and concentration. © 1969 The American Physical Society.
