The measured elastic scattering angular distributions were fitted with optical model calculations, and reaction cross sections were extracted. The same data were also analyzed using both global optical model potentials (Global OMP) and microscopic São Paulo potentials (SPP), to obtain the reaction cross sections. The data available in the literature for ⁹Be projectile includes the elastic scattering angular distributions, <em>α</em> production cross sections, and complete fusion cross sections on these and other targets at several energies are also utilized for comparative studies. The reaction cross section extracted from the three potentials (Best Fit, Global OMP and SPP) are in reasonable agreement for all the targets except for the energies below the barrier where the results from SPP deviate by 30-50%. Inclusive <em>α</em> particle production cross sections were also extracted by integrating the <em>α</em> particle angular distributions. The present data and data available from literature of reaction and <em>α</em>-particle production cross sections were utilized to make systematic studies. Systematics of reaction and <em>α</em>-particle production cross sections revealed their universal behavior. The ratio of complete fusion (CF), inclusive <em>α</em> cross sections, and their sum (CF+<em>α</em>) to reaction cross sections show that at sub-barrier energies inclusive <em>α</em> dominates and above barrier CF dominates, and cumulative of these two processes almost explains the reaction cross section at all energies over a wide range of target mass. A comparative study of <em>α</em> production with other weakly bound projectiles is also performed and a clear distinction between projectile types is observed, which is found to correlate well with <em>α</em> separation energies of the projectiles.</p></div>","PeriodicalId":19246,"journal":{"name":"Nuclear Physics A","volume":"1046 ","pages":"Article 122864"},"PeriodicalIF":1.4,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140279257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, direct measurement of these cross-sections is challenging. In this study, we proposed a method for estimating the total flux-weighted average formation cross-section of ^180m+gTa based on GEANT4 modeling to evaluate the short-lived (ground) and long-lived (metastable) states of ¹⁸⁰Ta. A Ta target was irradiated by a bremsstrahlung photon beam (maximum electron energy: 20 MeV) obtained from the linear electron accelerator LUE-75 at the A.I. Alikhanyan National Science Laboratory (AANL), Armenia. The experiment was performed using the activation technique, and the proposed GEANT4 simulation-based method was employed to evaluate the flux-weighted average formation cross-section of ^180mTa. In addition, the isomeric cross-section ratio for the ^180m,gTa isomeric pair was calculated. The theoretical results obtained using the TALYS 1.96 and EMPIRE 3.2 codes were consistent with the experimental ones. To the best of the authors’ knowledge, this paper reports the estimated flux-weighted average formation cross-section of ^180mTa and isomer ratio for the ^180m,gTa isomeric pair, induced by the irradiation of a bremsstrahlung beam with an end-point energy of 20 MeV, for the first time.
