Evaluation of Cross Sections of ~(63)Cu and ~(65)Cu for JENDL High Energy File

摘要

Cross sections of ~(63)Cu and ~(65)Cu for neutron and proton induced reactions have been evaluated up to 3 GeV for the High Energy File of Japanese Evaluated Nuclear Data Library (JENDL-HE). Different theoretical model codes were employed in this evaluation. For intermediate energy region between 20 and 150 MeV, GNASH based on statistical Hauser-Feshbach and preequilibrium models was used. Transmission coefficients calculated with DWUCK were used in the GNASH calculations of particle and photon emission cross sections and isotope production cross sections up to 150 MeV. The input parameters for the model codes were determined through analysis of experimental data in this energy region. For high-energy region between 150 MeV and 3 GeV, the JQMD-GEM code based on Quantum Molecular Dynamics (QMD) with statistical decay model (GEM) was employed. For energy region below 20 MeV, the existing JENDL-3.3 data were adopted. Several isotope production cross sections above 20 MeV were analyzed using the GMA code based on the generalized least-squares method or empirical fits in which experimental data were available. The results were compared with available experimental data as well as integral experiments such as thick target neutron yields.
