摘要：

We report a successful experimental test of an interferometer for cold neutrons using multilayer mirrors. Interference fringes that are analogous to the Brewster's fringes in classical optics have been clearly observed using the cold neutron beam with a wavelength of 12.6 Angstrom and a bandwidth of 3.5% at full width at half maximum. The observed interference fringes demonstrate the coherence of the reflection off the multilayer neutron mirror and confirm the feasibility of cold neutron interferometry using multilayer mirrors.
