摘要：

A nuclear polarimeter based on the low energy analyzing power of the Li-6(p, He-3) alpha-reaction has been developed and tested for proton energies below E(p) = 300 keV. The polarimeter uses a (LiF)-Li-6 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-degrees for the Li-6(p, He-3) alpha-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.
