Determination of nuclear excitation functions of zirconium using certain level density parameters for neutron-induced reactions

Investigation of nuclear reaction mechanisms of Nickel isotopes at various energies induced by alpha particles

“…The theoretical pre-compound reaction cross section values started from 46.1 MeV and it continues increasing as the energy of the alpha particle's energy increases [12]. Experimental results show that the graph starts at 34 mb with the same projectile energy of the theoretical reaction cross-section and it almost remains increasing throughout the course of the specified incident energies.…”

“…From table 5 and figure 5, it is evident that both the pre-equilibrium and compound nuclear reaction mechanisms are far from the experimental values thought the specified incident energies [12]. Compound reaction cross section shows that the graph starts at 673.6 mb and then the graph almost decreases by making a long tail.…”

“…In this study, the researchers tested the prediction capability of the theoretical nuclear reaction cross-section using computer code COMPLET. The code run with the default input parameters by considering all possible reactions involved including the reaction thresholds at the given bombarding energies [12,18]. Calculations for the experimental cross-section were made by using EXFOR datacentre in the literature.…”

“…The correlation coefficient of the cross section of experimental and pre-equilibrium nuclear reactions is calculated to be r=0.89 and the correlation coefficient between the experimental and the compound cross section nuclear reactions is calculated to be r=0.84 which describes the strong positive correlation between the theoretical and experimental total cross-section values [4,12].…”

“…Based on this research gap, the aim of this study is to investigate the reaction cross-section mechanisms of 58 Ni isotopes induced by alpha particle using computer code COMPLET and EXFOR database. The results of theoretical excitation function have been compared with the available experimental data taken from EXFOR database [12].…”
