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.
