The Disintegration of Carbon by Deuterons

Abstract

The excitation curves for the emission of $\ensuremath{\gamma}$-rays, neutrons, and protons from the disintegration of ${\mathrm{C}}^{12}$ by deuterons were investigated. Resonances for $\ensuremath{\gamma}$-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 $\ensuremath{\gamma}$-rays from ${\mathrm{C}}^{12}$ were shown to come from the reaction ${\mathrm{C}}^{12}(d,p){\mathrm{C}}^{13*}$. 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\ifmmode\pm\else\textpm\fi{}0.07 Mev. The excitation curves for the emission of $\ensuremath{\gamma}$-rays and protons from the disintegration of ${\mathrm{C}}^{13}$ by deuterons were investigated. Both curves showed a resonance at 1.55-Mev deuteron energy. The $\ensuremath{\gamma}$-rays from ${\mathrm{C}}^{13}$ have an energy of 5.5 Mev and come from the reaction ${\mathrm{C}}^{13}(d,n){\mathrm{N}}^{14*}$. The low energy group of neutrons from this reaction were found when a 23-percent ${\mathrm{C}}^{13}$ 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.
