Spectroscopy of the helium 2 3S - 2 3P transition above 0.01 Tesla - Application to optical pumping studies

Abstract : Optical pumping of helium makes use of the 2 S-3-2 P-3 transition at 1083 nm. We report on a study of this transition in magnetic fields up to 1.5 T. Based on these results, an optical method to measure nuclear polarisation in arbitrary field has been developed. Preliminary results on optical pumping at 0.1 T are presented.
