Abstract

An effective polarizer for thermal and epithermal neutrons is possible with polarized, high density, gaseous 3He. We describe the technique of 3He polarization by spin exchange with laser optically pumped Rb vapor which can provide 6 cm3of > 70% polarized 3He at a density of 3×1020 atoms cm-3 (10 atm at STP). The 3He polarization can be rapidly reversed, a requirement for sensitive symmetry tests.
