(167)Tm (T(1/2)=9.25d) is a candidate radioisotope for medical therapy and diagnostics due to its Auger-electron and low-energy X- and gamma-ray emission. Excitation functions of the (167)Er(p,n)(167)Tm reaction and (168)Er(p,n)(168)Tm, (167)Er(p,2n)(166)Tm, (166)Er(p,2n)(165)Tm disturbing reactions were measured up to 15MeV by using the stacked foil irradiation technique and gamma-ray spectroscopy. The measured excitation functions agree well with the results of ALICE-IPPE, EMPIRE-II and TALYS nuclear reaction model codes. The thick target yield of (167)Tm in the 15-8MeV energy range is 6.9MBq/microAh. A short comparison of charged particle production routes of (167)Tm is given.
（167）Tm（半衰期T(1/2)=9.25天）因其俄歇电子以及低能X射线和γ射线发射，是一种用于医学治疗和诊断的候选放射性同位素。利用叠层箔辐照技术和γ射线能谱，测量了（167）Er（p，n）（167）Tm反应以及（168）Er（p，n）（168）Tm、（167）Er（p，2n）（166）Tm、（166）Er（p，2n）（165）Tm干扰反应的激发函数，测量范围高达15MeV。测量得到的激发函数与ALICE - IPPE、EMPIRE - II和TALYS核反应模型代码的结果吻合良好。（167）Tm在15 - 8MeV能量范围内的厚靶产额为6.9MBq/μAh。给出了（167）Tm带电粒子产生途径的简要比较。
