Language：English Publisher：ELSEVIER SCIENCE BV

For use as a spin analyzer for low energy neutrons, a polarized He-3 gas system was developed at KEK. The polarization attained of He-3 at 3 atm determined as P-He = 40%, through the measurement of the transmission of unpolarized neutrons through the He-3 fell. The He-3 cell was used in the measurement of P-violating spin rotation of neutrons in the 0.734 eV p-wave resonance of the La-139+n system. As a result, a parity mixing matrix element xW = 1.04 +/- 0.40 meV was obtained. which is in agreement with the s- and p-wave resonance mixing model. An attempt is under way to improve the performance of the spin analyzer, by increasing the He-3 pressure and incorporating high-power diode lasers. So far we have obtained P-He = 12% at 20 atm.
