摘　　要：为计算^(186)W(p,n)^(186)Re^g反应的激发函数,收集了EXFOR实验数据库中的一些实验数据并对其进行了分析修正。将修正过的实验数据与EMPIRE程序理论计算得到的数据进行了比对,以此来选择合适的光学模型势和能级密度参数,给出了^(186)W(p,n)^(186)Re^g反应截面的推荐值。利用得到的激发函数计算了医用放射性核素186 Reg的厚靶产额,并给出了相应的推荐值。For calculating the excitation function of 186 W （p ,n ）186 Reg reaction , some experimental data in EXFOR data base were collected and evaluated .After comparing the evaluated data with the theoretical data calculated by the EM PIRE code ,the proper optical model potential and the level density parameters were chosen .Then the recom‐mended value of the reaction cross section and the thick target yield were given .Using the excitation function ,the thick target yield for the therapeutic radioisotope 186 Reg was calculated and the recommended value was given .
