考虑特征γ射线分支比、衰变常量和标准截面等修正,对氘引起的核反应^(186) W(d,p)187 W和^(186) W(d,2n)^(186) Re的激发函数进行了研究。收集并分析了这些反应激发函数的实验测量数据,应用数学方法对分析处理后的实验数据进行了拟合。同时,采用TALYS程序对这些激发函数进行了理论计算。经过综合评价,给出了50 MeV以下^(186) W(d,p)187 W和^(186) W(d,2n)^(186) Re反应激发函数的推荐值,利用得到的^(186) W(d,2n)^(186) Re激发函数推荐值计算了医用放射性核素^(186) Re的厚靶产额。

The deuteron-induced excitation functions for ^186 W（d,p）^187 W and ^186 W（d,2n）^186 Re reactions were evaluated with the correction ofγ-ray branch ratio,radioactive decay constant and standard cross sections.The available experimental data for these reactions were collected and analyzed.The experimental data of analysis and treatment were fitted using mathematical method.Simultaneously,the excitation functions for^186 W（d,p）^187 W and ^186 W（d,2n）^186 Re reactions were calculated using TALYS code.The recommendations of excitation functions for ^186 W（d,p）^187 W and ^186 W（d,2n）^186 Re reactions below 50 MeV were obtained after comprehensive evaluation.The thick target yields of the medical radioisotope ^186 Re were calculated using the recommended excitation function of ^186 W（d,2n）^186 Re reaction.
