摘　　要：通过对58Ni(n,2n)反应大量实验数据的收集、分析以及评价,给出了在20Me V以下的实验数据的评价截面和协方差矩阵,为最终给出推荐的58Ni(n,2n)截面数据和高可信度的协方差数据提供了基础。After the experimental data of reaction cross section about 58 Ni were collected through extensive col-lection,careful analysis and reasonable evaluation,this article presents the evaluation of experimental data andthe covariance matrix under 20 Me V.What we did provides the basis for the data of cross section values and cova-riance matrix of high reliability of 58Ni（n,2n）,which is the final recommendation.

关 键 词：实验核数据 截面 协方差
