用活化法测量了386 MeV的Bi和Co的中子活化截面。利用7Li（p，n）反应产生了准单能中子束。这些中子的能谱有一个高能峰（386 MeV）和一个低能尾。两个中子束，从质子束轴0°和25°，用于样品照射，使低能中子的贡献的校正。通过从0°辐照的反应速率中减去25°辐照的辐照样品的反应速率来估计中子诱导活化截面。测量的截面与其他研究的结果进行了比较，评价有关的核数据文件和计算数据的粒子和重离子输运代码系统代码。
Neutron activation cross sections for Bi and Co at 386 MeV were measured by activation method. A quasi-monoenergetic neutron beam was produced using the7Li(p,n) reaction. The energy spectrum of these neutrons has a high-energy peak (386 MeV) and a low-energy tail. Two neutron beams, 0° and 25° from the proton beam axis, were used for sample irradiation, enabling a correction for the contribution of the low-energy neutrons. The neutron-induced activation cross sections were estimated by subtracting the reaction rates of irradiated samples for 25° irradiation from those of 0° irradiation. The measured cross sections were compared with the findings of other studies, evaluated in relation to nuclear data files and the calculated data by Particle and Heavy Ion Transport code System code.
