A search for nEDM and new constraints on short-range “pseudo-magnetic” interaction using neutron optics of noncentrosymmetric crystal

Abstract New approach to measure both neutron electric dipole moment (EDM) and short-range pseudomagnetic nucleon-nucleon interaction using neutron optics of a crystal without center of symmetry is presented. This approach allows getting best direct constraint on the parameters of short range pseudomagnetic interaction of a free neutron with matter for the range of interaction distances λ 10 - 7  m.
