Spectroscopy of ultracold neutrons using diffraction by a moving grating

摘要

Spectra of ultracold neutrons that appeared in experiments on neutrondiffraction by a moving grating were measured using the time-of-flight Fourierspectrometer. Diffraction lines of five orders were observed simultaneously.The obtained data are in good agreement with the theoretical predictions basedon the multiwave dynamical theory of neutron diffraction by a moving grating.
