摘　　要：利用多能级Breit-Wigner公式对60Ni的全截面进行了计算,并将计算结果与BNL-325（四版）进行比较.利用实验核数据库EXFOR提供的全截面数据及实验条件,对60Ni的可分辩区实验全截面进行了评价,推荐出一套可用于校验共振参数的实验全截面数据并与计算结果进行了比较.By the use of Multilevel Briet-Wigner formula we conduct the calculation on total cross sections of 60Ni, and the result was compared with BNL-325 (4th Ed.). By the data of total cross sections and the experimental condition supplied by experimental nuclear data library EXFOR, an evaluation of experimental total cross section in resolved resonance region of 60Ni was given. A set of experimental cross sections data used in the verification of the resonance parameters was recommended, and it was compared with our calculating results.
