Popis: We report new experiments on the transverse and longitudinal spin dynamics of liquid 3 He polarized by an 11.3T field. At the lowest temperatures probed, the transverse spin diffusion coefficient saturates with an apparent anisotropy temperature of Ta=12±2 mK. This temperature dependence is in accord with the general idea of spin-diffusion anisotropy but the value of Ta is half that expected from extrapolating earlier experiments at a lower field. Strong magnetostatic effects in the form of long-lived spin modes are also observed for small gradients and small tipping angles.
