摘要：
In the present paper a new kind of neutron De Broglie wave leaky coupler-guide structure is proposed. This new magnetic coupler allows only one neutron polarization to be coupled into a magnetic neutron thin film waveguide. It is shown theoretically that this new thin film coupler decrease considerably the losses due to the roughness of the interfaces of the multilayer structure. Moreover a transmitted resonance peak is observed in a wavelength region accessible only for guided neutron waves. Thus a magnetic neutron coupler is proposed and a transmitted polarized neutron guided wave is observed experimentally. (C) 1997 American Institute of Physics.
