Polarized 3He, a promising method for the filtering of the neutron spin, is becoming a reality owing to the development of optical pumping methods and new solid state lasers. We have used a fully polarized neutron beam of 0.84Å wavelength to monitor the 3He polarization in a Rb/ 3He gas mixture pumped with a titanium-sapphire laser.
