本文介绍了一种采用四个独立多层膜反射镜的冷中子干涉仪。我们观察到的干涉条纹的对比度为60%。该干涉仪是基于一对使用标准具的设备，其中空气间隙为9.75 μ m的间距。光学系统等效于Jamin型干涉仪，其允许比先前类型的多层干涉仪大得多的两个相干光束之间的空间分离，以拓宽中子干涉测量的适用性。
A cold-neutron interferometer using four independent multilayer mirrors is demonstrated. We have observed interference fringes with a contrast of 60%. The interferometer is based on a pair of devices using etalons with an air gap of 9.75 {mu}m in spacing. The optical system is equivalent to the Jamin-type interferometer, which allows much larger spatial separation between the two coherent beams than the previous type of multilayer interferometer to broaden the applicability of neutron interferometry.
