Large enhanced P violation in a nuclear resonance reaction has been observed by using a polarized neutron beam. Enhanced CP violation is predicted to exist within the same nuclear reaction. We are now preparing to supply a polarized neutron beam for a CP violation search experiment. In the enhancement process of CP violation, we assume that the P violation of the compound nuclear state doesn't depend on the final state. However this assumption has not been verified yet. We plan to verify the assumption by measuring the 139La(n,g ) reaction with a polarized neutron beam at J-PARC MLF BL04. The supplied neutron beam will be polarized by using 3He spin filter, which will be installed into BL04. We present the states of development for 3He spin filter and study of the equipment in BL04.
