Book Description
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.

Measurement of the Cross Sections of Inelastic Neutron Collisions with the Nuclei of Chromium, Iron, Nickel, Niobium, and Molybdenum at Energies to 2.6 Mev

Book Description
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).
