“…The nuclear reaction cross sections induced by different energy neutrons and photons remains a major problem in applications such as data evaluation [6], applied nuclear physics, nuclear models, and nuclear reaction codes [7]. Therefore, an experimental study on the input parameters for nuclear reaction codes is necessary [8].…”

The cross sections of the 59Co(n, x) reaction in the average energy range of 15.2-37.2 MeV were measured using activation and an off-line γ-ray spectrometric technique. The neutrons were generated from the 9Be(p, n) reaction with proton beam energies of 25-45 MeV at the MC-50 Cyclotron facility of the Korean Institute of Radiological and Medical Sciences (KIRAMS). Theoretical calculations of neutron–induced reactions on 59Co were performed using the nuclear model code TALYS-1.9. The results for the 59Co(n, x) reactions were compared with the theoretical values obtained using TALYS-1.9 and the literature data provided in EXFOR and the TENDL 2019 nuclear data library. The theoretical values obtained using TALYS-1.9 with adjusted parameters are comparable to the experimental data. The measured reaction cross sections of a few radionuclides are new, and the others are comparable to the literature data, and thus, they can strengthen the database. The present study on cross sections leads to useful insight into the mechanisms of 59Co(n, x) reactions.

“…Up to date, the independent particle model of Fermi gas (FG) model after the Bethe's LD expression [3] and its various modifications [4,5,6] are frequently used in describing the corresponding experimental data including the LD of discrete energy levels and s-wave neutron resonance densities, as well as in the description of nuclear reaction product particle spectra [7][8][9][10][11][12][13]. The so-called composite Gilbert-Cameron (GC) model [4,2,13] unifies further FG model with the constant temperature (CT) approximation. These models however do not involve the collective excitation mechanism of the nucleus in the form of collective vibrations and rotation effects in an explicit manner, despite these effects may be described somehow by the LD parameter (a) and the concerning energy shift (∆).…”

In this work, the reliability of the Landau expression for the nuclear level density calculations is tested, for the first-time, to describe nuclear level densities of some light, intermediate mass and heavy nuclei at excitations corresponding to discrete and s-wave neutron resonance energies. The χ 2 minimizing method is used in treatment of the experimental data for the two suggested energy range of discrete energies given by Nuclear Data Sheet [1] and by the systematic for nuclear level density parametrization in [2]. Our comparison with the related data in the discrete energy range has shown that the results obtained by the Landau expression are better than those of back-shifted Fermi-gas model and constant temperature approximation. This result is also valid for some nuclei of interest when the s-wave neutron resonance level density is included to check theoretical prescriptions in the energy range from initial bound states to unbound states near the neutron binding energy.
