ABSTRACT
|
The excitation function of the 58Ni(n, p)58Co reaction was measured using the well established neutron activation technique and γ-ray spectroscopy. Neutrons in the energy range of 1.7 to 2.7 MeV were generated using the 7Li(p, n) reaction. The neutron flux was measured using the standard 115In(n, n′)115mIn monitor reaction. The results of the neutron spectrum averaged cross-section of 58Ni(n, p)58Co reactions were compared with existing cross-section data available in the EXFOR data library as well as with various evaluated data libraries such as ENDF/B-VIII.0, JEFF-3.3, JENDL-4.0, and CENDL-3.2. Theoretical calculations were performed using the nuclear reaction code TALYS. Various nuclear level density (NLD) models were tested, and their results were compared with the present findings. Realistic NLDs were also obtained through the spectral distribution method (SDM). The cross-section results, along with the absolute errors, were obtained by investigating the uncertainty propagation and using the covariance technique. Corrections for γ-ray true coincidence summing, low-energy background neutrons, and γ-ray self attenuation were performed. The experimental cross-section obtained in the present study is consistent with previously published experimental data, evaluated libraries, and theoretical calculations carried out using the TALYS code. |
