Interference filter for ultracold neutrons
Antonov A.V., Isakov A.I., Mikerov V.I., Startsev S.A.
We describe an interference filter for neutrons with energy ~ 1(Г8-10" eV. The filter consists of alternating layers of two different substances. The development and production of this filter can be of interest when it is necessary to filter out neutrons of required energy, and also to produce a neutron spectrometer with high resolving power in the indicated energy region.
