Effects of some level density models and γ-ray strength functions on production cross-section calculations of ^16,18O and ^24,26Mg radioisotopes

Abstract

Oxygen and magnesium isotopes can be used in nuclear reactor materials as cooling, shielding, coating, electronics etc. They can also occur through nuclear reactions during the reactor operation. The exposure of high energy gamma can change the material and its properties, and hence its objective of selection may not remain satisfied. Thus, it is required to study the cross section of different reactions on nuclear reactor materials to understand their sustainability for the properties, for which they are chosen. In the scope of this study, theoretically, different level density model calculations and γ-ray strength functions have been performed for (γ, p) reaction for 16,18O and 24,26Mg nuclei using TALYS 1.9 and EMPI˙RE 3.2.2 codes. Also, semi empirical (γ, p) formula by Tel et al., have been calculated and compared with all results. The effect of different level density models defined in these codes on gamma strength has been studied. Finally, the consistency of these obtained data with EXFOR data have been investigated.

Investigation of the Cross Sections and Effect of Level Density Models for Platinum Element

“…Nuclear reaction codes for the degradation of the compound nucleus are an advantage way to guess and evaluate yield for dissimilar reactions. There are experimental (Vagena and Stoulos 2017), (Stoulos and Vagena, 2018), (Ghergherehchi et al 2012), (Hu et al 2022), (Sziki et al 2006 (Kaplan et al 2014), (Aydın et al 2015, (Kaplan et al 2015), (Özdoğan et al 2018), (Artun 2018), (Artun 2019), (Sarpün et al 2019), (Canbula et al 2014, (Canbula 2020), (Noori et al 2019), (Noori et al 2017), , (Noori et al 2016), (Karpuz 2016), (Noori et al 2018), (Kavun and Makwana 2021), , (Kavun and Makwana 2020) nuclear reaction section studies in the literature that conducted in the light of this direction. The deuteron induced reactions play an important role in the accelerator based high intensity neutron sources (d-Be, d-Li).…”
