Activation cross sections of deuteron induced nuclear reactions on (169)Tm were measured up to 20 MeV by using the stacked-foil technique. Special emphasis was on production of the internal radiotherapy related radionuclide (169)Yb. No earlier experimental cross-section data on deuteron induced reactions on (169)Tm were found in the literature. The experimental data were compared with the results of the nuclear model codes ALICE-IPPE and EMPIRE-II. The integral yield of the (169)Tm(d,2n)(169)Yb reaction was deduced over the optimum energy range Ed = 20-->9 MeV. At 3.8 MBq/microA.h the yield is lower than that available from the commonly used (168)Yb(n,gamma) (169)Yb reactor method but on the other hand, it is higher than the yields from the earlier investigated (169)Tm(p,n)(169)Yb and (nat)Er(alpha,x) (169)Yb reactions.
利用叠层箔技术测量了能量高达20 MeV的氘核诱发的(169)Tm核反应的激活截面。特别关注与内放射治疗相关的放射性核素(169)Yb的产生。在文献中未发现关于氘核诱发(169)Tm反应的早期实验截面数据。将实验数据与核模型代码ALICE - IPPE和EMPIRE - II的结果进行了比较。推导了在最佳能量范围Ed = 20→9 MeV内(169)Tm(d,2n)(169)Yb反应的积分产额。在3.8 MBq/μA·h时，产额低于常用的(168)Yb(n,γ)(169)Yb反应堆方法，但另一方面，它高于早期研究的(169)Tm(p,n)(169)Yb和(nat)Er(α,x)(169)Yb反应的产额。
