P and T violation in slow neutron scattering
Description
Helicity dependence in the neutron radiative capture and the elastic scattering cross sections of 139La was examined by a simultaneous measurement of capture γ-ray intensity and neutron transmission. Significant helicity dependence was only in a p-wave resonance of 139La at En=0.734 eV. The longitudinal asymmetry in the p-wave resonance was AL,γ=(9.5±0.3)% and AL,n=(9.7±0.5)% for the capture γ-ray and the neutron transmission measurements, respectively. A possibility to measure T-odd correlations on polarized neutron transmission through a polarized lanthanum target is discussed. (author)
