| Abstract: | Optical phenomena that arise in the interaction of a neutron wave with matter characterized by a variable magnetic-induction vector are considered. Since the interaction is time-dependent, the neutron energy is not conserved. Only the neutron velocity component, which is orthogonal to the matter boundary, changes. The changes in the neutron energy and in direction of propagation are closely related to the reversal of the neutron-spin projection. Possibilities of application of the thin slab with rotating magnetization are considered. |
