“…The effect is essential when the path length of neutron in a medium is comparable or less than its wavelength. The effect was observed in [183] for isotope 157 Gd for which the real part of the neutron scattering length is much less than the imaginary one. Neutron reflection in this case is due to the latter.…”

“…It was decided to use not differential but integral method: thin layers of copper were deposited by thermal evaporation at the surface of float-glass plates, after irradiation and preparation of the sample the activity was measured as a function of total thickness of deposited copper. These experiments could be finished only much later after reconstruction of IRT-M reactor to IR-8 and construction of new UCN guide with H 2 O ice converter with the UCN flux density about 3 cm −2 s −1 [11]. It was shown that there is no abnormal propagation of the UCN wave function at least at the level 10 −5 .…”

“…This also leads to distortions in the spectrum. At the end of flight path 17, there is an all-wave UCN detector, described in [18], with a rotating disk 420 mm in diameter with a corrugated paraterphenyl scintillator and a 6 LiF radiator 700 µg/cm 2 thick evaporated onto it. Such a detector does not reflect neutrons [18].…”
