本文揭示了中子自旋干涉测量中观察莫尔条纹的判据。在以往的波前分割研究中，中子束必须经过细缝准直。另一方面，我们已经成功地观察到莫尔条纹的发散角为8.3毫拉德使用自旋偏振分割。基于部分相干理论的模型已经开发和实验验证。这些结果将为利用磁双折射操纵中子波阵面技术奠定基础。
We have revealed the criterion to observe moire fringes in a neutron spin interferometry. In former studies using wave front division, neutron beam had to be collimated by fine slits. On the other hand, we have succeeded to observe moire fringes with divergence angle of 8.3 mrad using spin polarization division. A model based on partial coherence theory has been developed and verified experimentally. These results will be the basis for neutron wave front manipulation technique using magnetic birefringence.
