| Abstract: | The effect of neutron spin rotation at Laue diffraction in a noncentrosymmetric weakly deformed neutron-transparent crystal has been studied experimentally. The effect appears because of two phenomena: (i) the interaction of the magnetic moment of a moving neutron with the crystalline electric field and (ii) bending of trajectories of the neutron in a deformed crystal; as a result, the amplitudes of two waves excited at Laue diffraction, which propagate in the crystal in opposite electric fields, at the output of the crystal are not equal. |
