Book excerpt: The time-of-flight technique was used with the ring scattering geometry in a laboratory with low neutron scattering background to measure the angular distributions of the cross sections for elastic and inelastic scattering of 14 MeV neutrons in natural chromium, iron, nickel, and niobium. Specifically for inelastic scattering included were: the 1.43 MeV and 4.56 MeV levels of 52Cr, the 0.85 MeV level, and (2.94-3.12) MeV and (4.46-4.51) MeV level groups of 56Fe, the 1.33 MeV level of 6°Ni combined with the 1.45 MeV level of 58Ni, and the 4.48 MeV level of 58Ni. Pulses of neutrons with time width of 0.9-1.1 ns were produced via the 3H(d, n)4He reaction in a 150 keV Cockcroft-Walton linear accelerator, with average intensities of 9x108 n/s. The energy of the incident neutrons was between 14.75 MeV (at 16°) and 13.48 MeV (at 160°). High purity scattering ring samples were used. The scattering angles ranged from (almost equal to)16° to (almost equal to)150°, for iron, chromium, and nickel, and from (almost equal to)16° to (almost equal to)160° for niobium, with a typical step of (almost equal to)10°. High purity ring samples were used.

ABRAMOV and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: All cross sections were calculated for a natural mixture of isotopes. In addition to the total cross sections for inelastic collisions, measurements were made for Nb and Mo the inelasticscattering cross section with excitation of two groups of levels. The average excitation energies were found from the energy of inelastically scattered neutrons, which proved to be equal to 0.8 and 1.0 Mev for Nb and 0.8 and 1.1 Mev for Mo. A comparison of the results obtained with the data of other authors shows that with an over-all agreement, there are individual divergences. The greatest divergences are observed between the works based on the recording of neutrons and the works with gamma-rays. (Author).

This book was released on 1974 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Measured neutron elastic and inelastic scattering cross sections for natural nickel between 4.07 and 8.56 MeV are presented and compared with the elastic differertial cross sections of Holmqvist and Wiedling and with ENDF/B III MAT 1123. The elastic differential cross sections are in general agreemert with those of Holmqvist and Wiedling but our angle-integrated differertial elastic cross sections are systemati cally higher by about 10% than those of Holmqvist and Wiedling above 4.6 MeV, a situation found in comparing the two sets of data for other elements. The ENDF/B II1 MAT 1123 elastic angular distributions are found to be in poor agreement with experimertal results from 4 to 8.5 MeV, though the ENDF/B III MAT 1123 angle-integrated differertial elasti c cross sections agree generally within experimertal uncertairties with our results over this energy range. Additional measurements of 6°Ni neutron elastic and inelastic scattering cross sections at 4.34 and 4.92 MeV are given and compared with previous results from 6 to 8.5 MeV and with natural nickel results. Agreement is shown to be excellent. Inelastic scattering cross sections to the 1.450 MeV level in sup 58/Ni are computed from the natural nickel and 6°Ni data. An evaporation model of inelastic scattering to levels of excitation energy in the residual nucleus below 6 MeV is found to be of questionable validity. (auth).
