Abstract

We have developed a new multilayer cold-neutron interferometer using a pair of beam splitting etalons (BSEs) with an air gap of 189 μm in spacing. This is the first multilayer neutron interferometer that separates two paths from each other completely without an overlap. Clear interference fringes with a contrast of 67% have been observed using a monochromatic cold-neutron beam with a wavelength of 0.88 nm.
