“…It can simulate nuclear reactions involving neutrons, photons, protons, deuterons, tritons, 3 He, and alpha-particles in the 1 keV-200 MeV energy range and for target nuclides of mass number range (12 < A < 339) [7]. Therefore, the TALYS code has been widely used in relevant research by most scientists [25][26][27][28].…”

The cross sections for the 94Zr(n,d*)93m+gY, 96Zr(n,γ)97Z, 96Zr(n,2n)95Zr, 90Zr(n,α)87mSr, 94Zr(n,α)91Sr,90Zr(n,p)90mY, 92Zr(n,p)92Y, and 94Zr(n,p)94Y reactions have been measured in the neutron energy range of 13.5-14.8 MeV by means of the activation technique. The neutrons were produced via the D-T reaction. A high-purity germanium detector with high energy resolution was used to measure the induced γ activities. In combination with the nuclear reaction theoretical models, the excitation curves of the above-mentioned eight nuclear reactions within the incident neutron energy range from the threshold to 20 MeV were obtained by adopting the nuclear theoretical model program system Talys-1.9. The resulting experimental cross sections were analyzed and compared with the experimental data from published studies. Calculations were performed using Talys-1.9 and are in agreement with our experimental results, previous experimental values, as well as results of the theoretical excitation curves at the corresponding energies. The theoretical excitation curves generally match the experimental data well.

“…As a mono-energetic γ-ray emitter, it also reveals the shape parameters of a detector spectrum, such as the peak-to-total ratio. As natural cobalt is a mono-isotopic ( 59 Co) element, its neutron-induced reaction cross sections are suitable for the verification, testing, and improvement of theoretical models [3,4]. Furthermore, the theoretical prediction of nuclear cross-section data is crucial in the absence of experimental data [5].…”

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.

“…Much attention has been paid earlier on topics like the exploration up to limits of the nuclear landscape and searching for the island of stability [16][17][18][19][20][21][22][23]. The terrestrial nuclear reaction experiments provide a large volume of data for thermonuclear reaction rates (mainly on stable targets), based on which many theoretical models have been developed to calculate the binding energy of different nuclides and the cross-sections and reaction rates for different nuclear processes [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. The JINA REACLIB database is a well-known source of thermonuclear reaction rates [43], updated continuously and snapshotted regularly by the JINA Collaboration which aims to compile a complete set of nuclear reaction rates.…”

Nucleosynthesis is a complex process in astro-nuclear evolution. In this work, we construct a directed multi-layer nuclear reaction network using the substrate-product method from a thermonuclear reaction database, JINA REACLIB. The network contains four layers, namely n-, p-, h-and r, corresponding to the reaction types involved in neutrons, protons, 4 He and the remainder, respectively. The degree values (i.e. numbers of reactions) for three layers of n-, p-and h-have a significant correlation with one another, and their topological structures exhibit a similar regularity. However, the r-layer has a more complex topological structure than others and has less correlation with the other three layers. A software package named 'mfinder' is employed to analyze the motif structure of the nuclear reaction network. We thus identify the most frequent reaction patterns of interconnections occurring among different nuclides. This work provides a novel approach to study the nuclear reaction network prevailing in the astrophysical context.
