摘要

97Ru 具有 215.7 千兆赫和 324.5 千兆赫的低能强γ射线,是诊断成像所需的关键放射性核素。目前正在不断研究产生这种放射性核素的新反应途径。进行此类反应的一个关键步骤是事先通过可靠的理论框架对放射性核素的生成截面和优化条件进行可靠的估计。为了了解 97Ru 的激发函数,我们对有关 α + 95Mo 反应的现有文献进行了新的研究。这些数据与不同射弹在中等质量目标上的其他反应进行了比较。使用了反应代码 pace4、empire-3.2.2 和 talys-1.96 来破译反应机理,并检验了基本理论模型的预测能力。理论模型还确定了不同射弹能量下的 97Ru 产率和最佳能量范围内的厚靶产率。

Theoretical analysis of light and heavy-ion induced reactions: production of medically relevant 97Ru
97Ru is a key radionuclide sought for diagnostic imaging due to its low-energy and intense γ-rays of 215.7 keV and 324.5 keV. New reaction routes to produce this radionuclide are constantly being investigated. A crucial step in carrying out such reactions is a reliable beforehand estimate of the production cross section of radionuclide and optimization conditions through robust theoretical frameworks. Existing literature on α + 95Mo reaction has been freshly examined to understand the excitation function of 97Ru. The data have been compared to other reactions of different projectiles on medium-mass targets. The reaction codes pace4, empire-3.2.2, and talys-1.96 have been employed to decipher the reaction mechanism and check the predictive ability of underlying theoretical models. The yield of 97Ru at different projectile energies and thick target yield in the optimum energy range has also been determined from the theoretical modeling.
