We report extensive experiments on the diffraction of very cold neutrons (A = 100 A) at large-area transmission phase gratings with grating constants d = 2km and d = 1 pm. respectively. The experimental results are compared with Fresnel-Kirchhoff calculations showing agreement in great detail. Using
A multilayer-mirror interferometer for very cold neutrons has been in progress for five years. This interferometer is analogous to a classical Mach Zehnder interferometer using multilayer mirrors as optical elements. The conditions required for the multilayer interferometer are presented, including
