Calculation of the neutron cross-section for iron group nuclei in ℓ≠0 case

Abstract

Total neutron cross-sections for iron group nuclei with energies [Formula: see text] have been theoretically calculated, for [Formula: see text] case. In this work, the collision matrix has been modified for a smooth spherical optical potential, which varies slowly with distance inside of target nucleus. Results agree well with the experimental data and TALYS 1.9 code. It has been found that a finite number of the angular momentum will contribute appreciably to the nuclear reaction. This study on smooth optical potential leads to useful insights into the mechanisms of neutron induced reactions, particularly for medium nuclei at high energies.
