| Outline of Final Research Achievements |
Neutron electric dipole moment (EDM) is an important probe to search for new physics beyond standard model. Search for EDM with crystal diffraction is advantageous according to the extremely strong effective electric field inside the crystal.
We observed Pendellosung interference fringes using pulsed cold neutrons in J-PARC for the first time. This means the establishment of the fundamental technique to search for the neutron EDM with crystal diffraction. We are continuing the development of the experimental setup with polarized neutron beamline to measure the internal electric field of the crystals. The measurement of the electric field in non-centrosymmetric crystal has been started.
