Abstract

We describe a method of

^{3} He

polarimetry relying on the polarization-dependent frequency shift of the Rb Zeeman resonance. Our method is ideally suited for on-line measurements of the

^{3} He

polarization produced by spin-exchange optical pumping. To calibrate the frequency shift we performed an accurate measurement of the imaginary part of the

Rb -^{3} He

spin-exchange cross section in the temperature range typical for spin-exchange optical pumping of

^{3} He .

We also present a detailed study of possible systematic errors in the frequency shift polarimetry.
