| Abstract: | To meet the need for nuclear data,the theoretical calculation of the covariance matrixes for the cross section data of(63)Cu is carried out based on the experimental neutron data and evaluation data of copper and it′s isotopes during the energy range from(99.5 keV) or threshold energy to 20.0 MeV,by using code NDCOV.FOR.The calculative data cover the shortage of the experimental data in reaction type and energy range,and supply reference for the design and construction of the nuclear project. |
