Cross sections of neutron-induced reactions

Abstract

We study the properties of the neutron-nucleus total and reaction cross sections for several nuclei. We have applied an analytical model, the nuclear Ramsauer model, justified it from the nuclear reaction theory approach, and extracted the values of 12 parameters used in the model. The given parametrization has an advantage as phenomenological optical model potentials are limited up to $150\ensuremath{-}200$ MeV. The present model provides good estimates of the total cross sections for several nuclei particularly at high energies.
