The Disintegration of Carbon by Deuterons

The excitation curves for the emission of γ-rays, neutrons, and protons from the disintegration of C¹² by deuterons were investigated. Resonances for γ-ray emission were found at 0.92, 1.16, 1.30, 1.43 and 1.74 Mev. The resonance at 1.43 Mev has a half-width less than 10 kev while the other resonances are considerably broader. Resonances for neutron emission were found at 0.92, 1.16, 1.30, 1.74 and 1.82 Mev. Resonances for proton emission are found at 0.92, 1.16, 1.23 and 1.74 Mev. The γ-rays from C¹² were shown to come from the reaction C¹²(d,p)C13*. The short range protons from this reaction were observed and had a range of 1.1 cm. The Q value for this 1.1-cm proton group is -0.52±{}0.07 Mev. The excitation curves for the emission of γ-rays and protons from the disintegration of C¹³ by deuterons were investigated. Both curves showed a resonance at 1.55-Mev deuteron energy. The γ-rays from C¹³ have an energy of 5.5 Mev and come from the reaction C¹³(d,n)N14*. The low energy group of neutrons from this reaction were found when a 23-percent C¹³ target was used. The Q value for this group of neutrons is 0.40 Mev. The relative and absolute yields of the various reactions were determined.
