Abstract
A nuclear polarimeter based on the low energy analyzing power of the 6Li(p, 3He)α reaction has been developed and tested for proton energies below E p = 300 keV. The polarimeter uses a 6LiF target evaporated on a water-cooled tantalum backing. The target is observed at backward angles by four silicon surface barrier detectors. The energy dependence of the analyzing power under 130° for the 6Li(p, 3He)α reaction has been determined down to 200 keV. Spin rotation has been observed via a magnetic field incorporated in a Wien filter demonstrating that the polarimeter is operational.
