We have measured the spin diffusion coefficient D for 3He-4He solutions of nominal 3He concentration x = 1.3% and 5.0% at pressures of ~0, 10 and 20 atm, and an x=8.5% solution at 4, 10 and 20 atm. The results are interpreted in terms of the Bardeen-Baym-Pines theory for 3He-4He solutions, and curves for the effective 3He-3He interaction V(k) are presented. We find no evidence for a minimum in V(k) at nonzero k. Weak coupling BCS pairing transition temperatures calculated from the V(k) lie in the range 10-6–10-7 K. |
