Evaluation of Cross Sections for Neutrons and Protons up to 3 GeV on 12,13C

Abstract

Cross sections of 12,13C are evaluated for both neutrons and protons with incident energies up to 3 GeV. The evaluation is based on predictions from nuclear‐model calculations and systematics as well as measurements. A nuclear‐model calculation‐code system is developed using the GNASH code for energies less than 150 MeV and the JQMD code for those above 150 MeV. The evaluated cross sections are as follows; neutron total cross sections, nucleon elastic scattering cross sections and angular distributions, nonelastic cross sections, production cross sections and double‐differential cross sections of secondary light particles (n, p, d, t, 3He, α, and π) and gamma‐rays, and isotope‐production cross sections. The results are compared with available experimental data and the other evaluation.
