摘要:

在系统研究医用放射性核素带电粒子产生途径的框架内,首次测量了40 MeV以下$^{nat}$ Hf($α$,xn)$^{178-178m}$ Ta核反应间接产生$^{178m}$ Ta的激发函数。同时,还评估了副反应$^{nat}$ Hf($α$,x)$^{179,177,176,175}$ W、$^{183,182,178g,177,176,175}$ Ta、$^{179m,177m,175}$ Hf。采用叠箔辐照技术和$γ$能谱法.新的实验截面数据的$^{nat}$ Ta(d,xn)$^{178}$ W反应也报告高达40 MeV。将测量的激发函数与ALICE-IPPE和EMPIRE核反应模型代码的结果以及TENDL-2013库中基于TPENS 1.4的数据进行比较。推导了$^{178}$ W的厚靶产额,并与其它带电粒子((p,4 n),(d,5 n)和($^3$ He,x))生产路线的产额进行了比较。

英文摘要:

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)$^{178-178m}$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.
