Excited States in N14 from C12(d, d)C12, C12(d, p0)C13, and C12(d, p1)C13*

Abstract

Excited states in the ${\mathrm{N}}^{14}$ nucleus have been observed by measuring the differential scattering and reaction cross sections of ${\mathrm{C}}^{12}(d, d){\mathrm{C}}^{12}$, ${\mathrm{C}}^{12}(d, p_0){\mathrm{C}}^{13}$, and ${\mathrm{C}}^{12}(d, p_1){\mathrm{C}}^{13*}$ for deuteron bombarding energies from 0.5 to 2.0 Mev. Resonances were investigated at deuteron bombarding energies of 0.92, 1.19, 1.31, 1.446, and 1.79 Mev, corresponding to excited states at 11.05, 11.29, 11.39, 11.503, and 11.80 Mev in ${\mathrm{N}}^{14}$. Scattering matrix analysis of the elastically scattered deuterons and of angular distributions of the reaction protons to the ground state of ${\mathrm{C}}^{13}$ gave assignments of $1^{+}$, $2^{-}$, $1^{+}$, $3^{+}$, and $1^{+}$ for these states. The analysis of the ${\mathrm{C}}^{12}(d, p_0){\mathrm{C}}^{13}$ angular distributions at 0.92, 1.19, and 1.31 Mev indicated a reaction mechanism in which the relative proton-neutron spin orientation of the deuteron is preserved.
