Cross-sections for the production of 181,182m,g,183,184g,186gRe radioisotopes from proton bombardment of natural tungsten have been measured using the stacked foil activation technique for proton energies up to 14.7 MeV. The results were analyzed and compared with the reported experimental data, and the theoretical excitation functions as calculated by the EMPIRE 3.2.3 and TALYS 1.9 codes. Several attempts have been made to reproduce the experimental excitation functions by different EMPIRE input parameters, and a reasonable agreement was attained. While measuring the activity of radionuclide 181Re, the intensity of the emitted 360-keV γ-photon was estimated at around 10%, about half of the value reported in various databases. The integral yield of the investigated radioisotopes has been calculated, and a particular interest in the 186gRe therapeutic radionuclide was discussed.

钨上质子诱发核反应的活化截面:特别关注 186Re 的形成

使用质子能量高达 14.7 MeV 的堆叠箔激活技术测量了通过质子轰击天然钨生产181,182m,g,183,184g,186g Re 放射性同位素的横截面。对结果进行了分析,并与报告的实验数据以及由 EMPIRE 3.2.3 和 TALYS 1.9 代码计算的理论激励函数进行了比较。我们多次尝试通过不同的 EMPIRE 输入参数来重现实验激励函数,并获得了合理的一致性。在测量放射性核素181 Re的活度时,发射的 360 keV γ 光子的强度估计约为 10%,约为各种数据库中报告值的一半。计算了所研究的放射性同位素的积分产率,并讨论了对186g Re 治疗放射性核素的特别关注。
