Production cross sections of Nb and Ta isotopes in the proton-induced reactions on (nat)Zr and (nat)Hf, respectively, were measured up to 14 MeV using a stacked-foil technique. The observed nuclides in the (nat)Zr(p,x) reactions were (90g,91m,92m,95m,95g,96)Nb, (95)Zr, and (87g,88)Y. In the (nat)Hf(p,x) reactions, (175,176,177,178,179)Ta and (175)Hf were observed. The obtained cross sections for each nuclide were compared with the previously reported data and with the theoretical cross sections calculated by the TALYS-1.4 code. Thick-target yields of the observed nuclides were deduced from the measured production cross sections.
分别使用叠箔技术测量了质子诱发（天然）Zr和（天然）Hf反应中Nb和Ta同位素的生成截面，测量能量高达14 MeV。在（天然）Zr(p,x)反应中观测到的核素为(90g,91m,92m,95m,95g,96)Nb、(95)Zr和(87g,88)Y。在（天然）Hf(p,x)反应中，观测到了(175,176,177,178,179)Ta和(175)Hf。将获得的各核素截面与先前报道的数据以及用TALYS-1.4代码计算的理论截面进行了比较。从测量的生成截面推导出观测核素的厚靶产额。
