(167)Tm is a candidate radioisotope for both nuclear medicine diagnostics and therapy due to its emitted Auger-electrons, low energy X- and gamma-rays. In the frame of a systematic study of excitation functions for production of medically relevant radioisotopes by charged particle induced reactions on rare earths, the (165)Ho(alpha,2n)(167)Tm reaction and the (165)Ho(alpha,n)(168)Tm, (165)Ho(alpha,3n)(166)Tm, (165)Ho(alpha,4n)(165)Tm side reactions were measured up to 40 MeV by the stacked foil irradiation technique and gamma-ray spectroscopy. The measured results were compared to the ALICE-IPPE and EMPIRE-II theoretical curves. Thick target yields, impurity levels and specific activities were deduced and compared with the same parameters for other charged particle production routes of (167)Tm.
由于铥发射俄歇电子、低能X射线和γ射线，它是一种适用于核医学诊断和治疗的候选放射性同位素。在通过稀土元素上的带电粒子诱导反应生产医学相关放射性同位素的激发函数系统研究框架内，利用叠层箔辐照技术和γ射线光谱学，对（165）钬（α，2n）（167）铥反应以及（165）钬（α，n）（168）铥、（165）钬（α，3n）（166）铥、（165）钬（α，4n）（165）铥副反应进行了测量，能量高达40兆电子伏。将测量结果与ALICE - IPPE和EMPIRE - II理论曲线进行了比较。推导了厚靶产额、杂质水平和比活度，并与（167）铥的其他带电粒子生产途径的相同参数进行了比较。
