Reflectometry with registration of secondary radiation at total neutron reflection (1911.03669v1)

Abstract: Neutron reflectometry is a method for measuring of the spatial dependence (profile) of the potential interaction between neutron and medium. At interface of media the interaction potential is the sum of the elements potentials. For definition of potentials of separate elements (isotopes) a secondary radiation is recorded. Recording channels of secondary radiation are created on spectrometer REMUR at pulsed reactor IBR-2 in Dubna (Russia). The results for testing of the channels are reported and perspectives of reflectometry with registration of secondary radiation are discussed
