Cross sections of alpha particle induced nuclear reactions on iridium were investigated using a 51.2-MeV alpha particle beam. The standard stacked-foil target technique and the activation method were applied. The activity of the reaction products was assessed without chemical separation using high resolution gamma-ray spectrometry. Excitation functions for production of gold, platinum and iridium isotopes (Au, Au, Au, Au, Au, Au, Au, Pt, Pt, Ir, Ir, Ir, Ir and Ir) were determined and compared with available earlier measured experimental data and results of theoretical calculations using TALYS code system. Cross section data were reported for the first time for the Ir(α,x)Au, Ir(α,x)Au, Ir(α,x)Pt, Ir(α,x)Pt, Ir(α,x)Ir, Ir(α,x)Ir, Ir(α,x)Ir and Ir(α,x)Ir processes. A possible production route for Pt, the potentially important radionuclide in nuclear medicine, is discussed.
利用51.2兆电子伏的α粒子束研究了α粒子与铱发生的核反应的截面。采用了标准的叠箔靶技术和活化方法。使用高分辨率γ射线能谱法在不进行化学分离的情况下评估反应产物的活度。测定了金、铂和铱同位素（Au、Au、Au、Au、Au、Au、Au、Pt、Pt、Ir、Ir、Ir、Ir和Ir）生成的激发函数，并与早期测量的可用实验数据以及使用TALYS代码系统的理论计算结果进行了比较。首次报告了Ir(α,x)Au、Ir(α,x)Au、Ir(α,x)Pt、Ir(α,x)Pt、Ir(α,x)Ir、Ir(α,x)Ir、Ir(α,x)Ir和Ir(α,x)Ir过程的截面数据。讨论了核医学中潜在重要的放射性核素铂的一种可能的生产途径。
