“…Literary data also confirm the generation of a significant number of secondary cascade gamma quanta from inelastic scattering reactions [14], from radiation and resonance capture reactions [12,[15][16]. But, at the same time, it should be borne in mind that the data on the multiplicity of secondary gamma quanta, if not specified, were accumulated by the spectrometric technique during a long-time interval, and were processed in a delayed time mode.…”

“…In the reactions of inelastic scattering (n, n'γ) in on heavy nuclei of scintillators, such as Bi, W, Gd, Cd, neutrons can lose energy up to 2-3 MeV on average, slowing down considerably. Along with inelastic scattering, neutrons are effectively slowed down in the elastic scattering reaction on light nuclei that are part of oxide scintillators, such as 16 O.…”

The results of the study of the contributions of the interaction reactions of fast neutron sources of 239Pu-Be and 252Cf to the counting efficiency of registration by oxide scintillators CdWO4, ZnWO4, Bi4Ge3O12 and Gd2SiO5, presented. The amount of gamma quanta per input neutron emitted from final nuclei excited in the reactions of inelastic scattering (n, nʹγ)in, resonant scattering (n, n)res and capture (n, γ)res and radiation capture (n, γ)cap was measured. PMT R1307 operating in single-electron mode was used as a photodetector, the background rate was ~ 5*103 s-1. The measured efficiency ε for scintillators ø40x40 mm was 752 for ZWO, 532 for CWO, 37 for GSO, and 23 for BGO in "counts/neutron" units, measurement error rate ~ 3-5%. The formation of the detector response is influenced by the parameters of the scintillator nuclei, such as the values of the interaction cross sections in the resonance region, the density of nuclear levels of the final nuclei, the lifetime of excited nuclear states, the upper limit of the resonance region of the cross section, as well as the scintillation time and geometric parameters of the scintillators. A phenomenological model of the response of an oxide scintillator to fast neutrons is proposed.

The differential cross section for the production of the 6.13 MeV gamma ray from the 16O(n,n'γ) reaction has been measured between the reaction threshold and 8.2 MeV. The gamma rays were detected with a large NaI(Tl) crystal using time-of-flight techniques. Angular distributions have been studied at two resonance energies in the cross section, viz. 6.87 and 7.82 MeV. Spins for the involved levels in the compound nucleus are proposed and the shapes of the angular distributions are compared with calculations based on the compound nucleus model. The results are also compared with previously reported measurements.
