Abstract

Scandium (Sc) radioisotopes have been attracting increasing attention in medical applications. ⁴⁷Sc, which has the potential for targeted radiotherapy, is quite promising as a candidate for theranostic pairing with the β⁺-emitting radioisotope ⁴³Sc or ^44gSc. The excitation functions for producing ^{43,44m,44g,46,47}Sc through (α,x) reactions on natural calcium (Ca) up to an energy of 25 MeV were experimentally measured and critically compared with previous experimental reports and theoretical data obtained by EMPIRE-3.2.3 code and from TENDL-2021 library. The physical yields for producing of ^{43,44m,44g,46,47}Sc through (α,x) reactions on ^natCa were determined using the measured production cross-section of the radionuclides and the stopping powers.

通过天然钙上（α，x）核反应生产 Sc 放射性同位素的激发函数，最高 25 MeV

钪（Sc）放射性同位素在医疗领域的应用日益受到关注。具有靶向放射治疗潜力的 47Sc 很有希望成为与发射 β+ 的放射性同位素 43Sc 或 44gSc 配对的治疗同位素。实验测量了天然钙（Ca）上通过（α,x）反应产生 43,44m,44g,46,47Sc（最高能量为 25 MeV）的激发函数，并将其与之前的实验报告以及 EMPIRE-3.2.3 代码和 TENDL-2021 库中获得的理论数据进行了严格比较。利用测得的放射性核素生成截面和停止功率，确定了通过（α,x）反应在天然钙上生成 43,44m,44g,46,47Sc 的物理产率。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. 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. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
