摘要：

The observations of large enhancement of parity-violation at p-wave compound resonance encourage prompt active discussion of TRI test in neutron optics. One of the most attractive objects for investigation is the p-wave resonance of (139)La at energy 0.734 eV for which the strongest P-odd effect of spin dichroism has been observed. A new technique of neutron spin analysis based on optically pumped (3)He spin filter has been applied successfully to measure the complementary effect of P-odd spin rotation near the same p-wave resonance of (139)La. The results obtained are consistent with theory predictions. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
