Time analysis of the elastic neutron scattering by the ⁵⁸Ni nuclei in the range 0.5–0.8 MeV

Abstract

The concept of time evolution was applied to the study of the neutron scattering by 58Ni nuclei. The interval of neutron energies from 500 to 800 keV was examined. The experimental data on the energy dependence of the total and differential cross sections and on the experimental-based resonance spaces and widths were used to determine the mean time delays and the time delay dispersions for the forward scattering. Both the energy autocorrelation function and the time probability density function for this process were calculated too. The time parameters were estimated for the diffraction part and the compound scattering components. The estimation of the average compound scattering cross section and the optical model volume absorption integral per nucleon have been done.
