Abstract
A single crystal chemical vapor deposited (sCVD) diamond detector is used as an active target to measure neutron-induced reactions on natural carbon using the neutrons produced by spallation, with a broad energy spectrum at LANSCE. The neutron-induced reactions are detected in the diamond as low as En=400 keV and up to approximately 100 MeV. Relative cross sections for C12(n,α0), C12(n,p0), C12(n,d0+p1), and C13(n,α0) are reported up to En=22 MeV and comparisons on detected pulse-height spectra and detector response of scattering reactions are made with GEANT4 simulations using the ENDF/B-VIII.0 evaluated nuclear data library up to 20 MeV. The results are compared with past experimental data, including other works that incorporate diamond detectors as an active carbon target. In addition, R-matrix calculations for the C13 + n system are presented.
