Abstract:It is pointed out that the equilibrium ratio of the nuclear spin polarizations of two 3He systems in contact is proportional to the ratio of their volume susceptibilities and inversely proportional to the ratio of their densities. Hence the polarization of dilute 3He-4He solutions can be enhanced by 40% or more over the polarization of pure 3He.
