Optical Potential Barrier Transparency for the Fast Neutron

The transparency of the spherical optical potential barrier to an incident neutron with energy between 70 and 200 MeV has been calculated. The spherical optical barrier transparency for neutrons in the presence of angular momentum with iron group nuclei is calculated in this work by modifying the collision matrix. In addition, the neutron-nucleus cross section is calculated. The results were compared with the experimental data and theoretical values obtained using the nuclear model TALYS-1.96 code, and a good agreement was found. The nuclear reaction will be significantly influenced by a finite number of the angular momentums \(\ell=1\) , \(2\) , and \(3\) . The current study on transparency provides important new knowledge on the workings of neutron-induced processes.
