Description
Using measured spin-transfer rates from alkali-metal atoms to 3He, combined with spin-relaxation rates of the alkali-metal atoms due to 3He and 4He, it should be possible to differentiate between isotropic and anisotropic spin exchange. This would give a fundamental limit on the 3He polarization attainable in spin-exchange optical pumping. For K-He, we find the limit to be 0.90±0.11.
