Abstract

We calculate the longitudinal magnetic relaxation timeT 1 –1 for a dilute, polarized Fermi gas with short range interactions at low temperatures. In the limit of small polarizationsT 1 –1 is proportional toT –2 in agreement with earlier predictions, while in the opposite caseT 1 –1 is strongly affected by polarization, and in the limit of large polarizations becomes proportional to the square of the energy separation between the Fermi surfaces for up and down spins. The possibility of measuringT 1 in dilute solutions of 3 He in superfluid 4 He is investigated.
