Sp. Dmitriev et al., OBSERVATION OF ORIENTED 2(3)S(1) HELIUM-ATOMS IN A SODIUM-HELIUM PLASMA IRRADIATED BY POLARIZATION-MODULATED LASER-RADIATION, JETP letters, 65(5), 1997, pp. 399-401
An experiment on the observation of spin polarization of metastable he
lium atoms interacting with optically oriented sodium atoms under cont
inuous rf discharge conditions is described. Laser radiation with alte
rnating-sign circular polarization, tuned to the resonance excitation
of the 3(2)S(1/2)-3(2)P(1/2) transition in Na atoms, is used as the so
urce for optical pumping of ground-state sodium atoms. (C) 1997 Americ
