Cross section data for the formation of 121,122,123,125,127 Xe via proton induced reactions on 127 I were critically analyzed. Three nuclear model codes (TALYS 1.9, ALICE-IPPE, and EMPIRE 3.2) were used to ensure the consistency and reliability of the experimental data. Utilizing a well-developed evaluation methodology, a recommended fit for each excitation function was obtained, based on theoretical predictions of nuclear models and experimental cross sections. By using the recommended/reference results, thick target yields were calculated for each production route and its associated impurity reactions. The indirect production of the radionuclides 121,122,123,125 I was explored. Special attention was paid to standardization of cross section data for the production of the medically important radionuclides 127 Xe and 123 I via the routes 127 I(p,n)127 Xe and 127 I(p,5n)123 Xe(EC, β+)123 I, respectively.

评估 127I(p,xn) 121,122、123、125,127Xe 反应的激发函数,特别是用于医疗用途的 127Xe 和 123I 的生产
批判性分析了通过 127I 上的质子诱导反应形成 121,122,123,125,127Xe 的横截面数据。使用了三个核模型代码(TALYS 1.9、ALICE-IPPE 和 EMPIRE 3.2)来确保实验数据的一致性和可靠性。利用成熟的评估方法,根据核模型和实验横截面的理论预测,获得了每个激发函数的推荐拟合。通过使用推荐/参考结果,计算了每条生产路线及其相关杂质反应的厚靶标产量。探索了放射性核素 121,122,123,125I 的间接生产。特别注意通过路线 127I(p,n)127Xe 和 127I(p,5n)123Xe(EC, β+)123I 分别生产医学上重要的放射性核素 127Xe 和 123I 的横截面数据的标准化。
