THE CROSS-SECTION MEASUREMENTS FOR ^(59)Co(n,p) ^(59)Fe, ^(59)Co(n,α) ^(56)Mn AND ^(59)Co(n,2n) ^(58)Co REACTIONS

本实验用活化法测量了中子能量在12.8MeV到17.8MeV的^(59)Co(n,p)^(59)Fe,^(59)Co(n,α)^(56)Mn,^(59)Co(n,2n)^(58)Co三个反应道的反应截面值,实验的测量误差在3.3％—6.9％范围内. 本文还计算了反应截面测量误差的协方差矩阵,并将实验测量值与理论计算值进行了比较.另外,还对上述三个反应道的截面进行编评,给出了推荐的激发曲线.

The cross sections of ^(59)Co(n,p)^(59)Fe, ^(59)Co(n,α)^(56)Mn and ^(59)Co(n,2n) ^(58)Co reactions have been measured at neutron energy region of 12.8 MeV-17.8 MeV by activation method. The coveriance matrix of measured errors was calculated, and the comparison between the values of measured and calculated using theory model was made. The evaluated excitation functions for the three reactions are given.
