| Abstract: | An experiment on the observation of spin polarization of metastable helium atoms interacting with optically oriented sodium
atoms under continuous rf discharge conditions is described. Laser radiation with alternating-sign circular polarization,
tuned to the resonance excitation of the 32

1/2–32
P
1/2 transition in Na atoms, is used as the source for optical pumping of ground-state sodium atoms.
