Moderately polarized liquid 3He at temperatures as low as 30 mK has been obtained using rapid melting of polarized solid. Viscosity measurements using a vibrating wire and measurements of the relaxation time constant T1 at 300 MHz are presented. A sharp change in T1 as a function of time has been observed, from a short T1 at the beginning of the decompression to a rather long relaxation time afterwards. The effective temperature dependence of T1 is given by T1∼T-1, while a T-2 dependence is expected for intrinsic relaxation. Initial viscosity measurements indicate an in-crease in viscosity with increasing polarization, but this is subject to further confirmation.
