“…Drake et al [5] measured an angular distribution at 7.5 MeV and showed that 4 ~( d o / d Q ) at 55' was a poor estimate of the total cross section. The value obtained at 90" was in agreement with that measured by Perkin [ 2 ] .…”

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.

“…Measurements of the total y-ray production cross-sections (sum of the discrete y-line yields and a continuous y-ray spectrum) were started in the work (6). The work was performed at Van-de-Graaf accelerator for the neutron energies of3.5, 5.5, 6.5, 7.5 and 8.5 MeV Gamma-radiation was detected by a three-crystal pair spectrometer on the basis ofNal(Tl)-scintillators under the angle of 90° to the axis of the charged particles beam.…”

Data on total y-ray production cross-sections from the evaluated data libraries ENDF, JENDL, BROND and others were comparatively analyzed. Total y-ray production cross-sections and discrete y-Iines were evaluated in the neutron energy range of 0.5-19 MeY. Also evaluated were angular distributions of discrete y-Iines with the energy 846.8, 1238.3 and 1810.8 keY. Evaluated data on coefficients of Legendre polynomials al, a4 were obtained describing angular distributions in the neutron energy range from the threshold ofthe level excitation of up to 14 MeY.

“…For neutron energies below about 3.5 MeV we have used the gamma-ray production cross sections of Montague and Paul, 32 from 3.5 to 8.5 MeV we have used the data of Perkin, 66 and at 14 MeV we have used the data of Caldwell et al 67 We have used graphical methods to bridge the gap between 8.5 and 14 MeV and extrapolate the data to 18 MeV (see Table 24).…”
