Abstract: The neutron yield in the 12C(d,n)13N reaction and the proton yield in the 12C(d,p)13C reaction have been measured using deuteron beams of energies 0.6–3 MeV. The deuteron beam is delivered from a 4-MeV electrostatic accelerator and bombarded on a thick carbon target. The neutrons are detected at 0o, 24o, and 48o and the protons at 135o in the laboratory frame. Further, the ratio of the neutron yield to the proton yield was calculated. This can be used to effectively recognize the resonances. The resonances are found at 1.4 MeV, 1.7 MeV, and 2.5 MeV in the 12C(d,p)13C reaction, and at 1.6 MeV and 2.7 MeV in the 12C(d,n)13N reaction. The proposed method provides a way to reduce systematic uncertainty and helps confirm more resonances in compound nuclei.
