Abstract

Cross section of medically important

^{47, 46, 44 g, 44 m, 43}

Sc radionuclides produced via alpha induced reactions on natural Calcium are estimated theoretically using statistical model calculations employing TALYS (version 1.96) code up to 30 MeV incident alpha particle energy. The most suitable level density model, alpha optical model potential and pre-equilibrium model for theoretical estimation of production cross section of each of the Sc isotopes have been investigated and effect of their simultaneous application have also been studied. The theoretical results have been compared to the experimental data taken from literature and the latest evaluations of TENDL-2023 libraries. Such systematic studies are extremely important for understanding the influence of different theoretical models on the production cross section of different radioisotopes and for validation of different nuclear model codes.

理论模型对natCa(α, x)47、46、44g、44m、43Sc反应截面影响的系统研究

利用TALYS（1.96版）代码进行统计模型计算，在30 MeV入射α粒子能量下，对天然钙上α诱导反应产生的医学上重要的47,46,44g,44m，43Sc放射性核素的横截面进行了理论估计。本文研究了最适宜的能级密度模型、α光学模型电位模型和预平衡模型，并对它们同时应用的影响进行了研究。将理论结果与文献实验数据和最新的TENDL-2023图书馆评价进行了比较。这种系统的研究对于理解不同理论模型对不同放射性同位素生产截面的影响和验证不同核模型代码是极其重要的。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
