In the frame of a systematic study of charged particle production routes of medically relevant radionuclei, the excitation function for indirect production of (178m)Ta through (nat)Hf(α,xn)(178)W-(178m)Ta nuclear reaction was measured for the first time up to 40 MeV. In parallel, the side reactions (nat)Hf(α,x)(179,177,176,175)W, (183,182,178g,177,176,175)Ta, (179m,177m,175)Hf were also assessed. Stacked foil irradiation technique and γ-ray spectrometry were used. New experimental cross section data for the (nat)Ta(d,xn)(178)W reaction are also reported up to 40 MeV. The measured excitation functions are compared with the results of the ALICE-IPPE, and EMPIRE nuclear reaction model codes and with the TALYS 1.4 based data in the TENDL-2013 library. The thick target yields were deduced and compared with yields of other charged particle ((p,4n), (d,5n) and ((3)He,x)) production routes for (178)W.
在对医学相关放射性核素带电粒子产生途径进行系统研究的框架下，首次测量了通过（天然）铪（α，xn）（178）钨 - （178m）钽核反应间接产生（178m）钽的激发函数，能量高达40 MeV。同时，还评估了副反应（天然）铪（α，x）（179,177,176,175）钨、（183,182,178g,177,176,175）钽、（179m,177m,175）铪。采用了叠层箔辐照技术和γ射线能谱法。还报告了（天然）钽（d，xn）（178）钨反应高达40 MeV的新实验截面数据。将测量的激发函数与ALICE - IPPE、EMPIRE核反应模型代码的结果以及TENDL - 2013库中基于TALYS 1.4的数据进行了比较。推导了厚靶产额，并与（178）钨的其他带电粒子（（p，4n）、（d，5n）和（（3）He，x））产生途径的产额进行了比较。
