Popis: Large enhanced P-violations was discovered in several compound nuclei. A mechanism of P- violation can be applied to enhancement of T-violation in compound nucleus. We plan the experi- ment for sensitive T-violation search, however, the mechanism of P-violation(s-p mixing) has not been verified in detail yet and the spin factor κ(J) has not been measured in candidate nuclei for T-violation search. We need to measure angular distributions in the (n,γ) reaction for verification of s-p mixing and determination of κ(J) as a feasibility study for the T-violation search. The (n,γ) reaction of 139La which is one of the candidate nuclei was measured with 4π germanium spectrometer in J-PARC/MLF/ANNRI. A neutron spectrum and a γ-ray spectrum for 139La was obtained.
