Production of ultracold neutrons (UCN) by single-phonon downscattering of cold neutrons from superfluid helium (the ''superthermal process'') utilizes input neutrons only in a narrow wavelength band around 0:89 nm: Delivering a monochromatic 0:89 nm neutron beam to a superfluid helium target reduces
