Endothermic Deuteron Stripping Reactions. II.C12(d, p3γ)C13*Reaction

Abstract

The total cross section of the ${\mathrm{C}}^{12}(d, p_3){\mathrm{C}}^{13}$ reaction ($Q=-1.13\mathrm{}$ Mev) to the third excited state of ${\mathrm{C}}^{13}$ at 3.85 Mev was measured for deuteron energies between 1.7 and 3.1 Mev. The cross section was obtained from the yield of the 170-kev $\gamma$ ray corresponding to the electric-dipole transition between the $\frac{5}{2^{+}}$, ${\mathrm{C}}^{13}$ 3.85-Mev level and the $\frac{3}{2^{-}}$, ${\mathrm{C}}^{13}$ 3.68-Mev level. The angular distribution of the 170-kev $\gamma$ ray relative to the deuteron beam was investigated for the same deuteron energy region by measuring yields at 0° and 90° to the beam. The measured anisotropy is compared to the predictions of plane-wave and distorted-wave stripping. The $\gamma$-ray anisotropy for deuteron energies between 1.7 and 2.4 Mev is in good agreement with the predictions of plane-wave stripping. Seven compound nucleus resonances corresponding to known ${\mathrm{N}}^{14}$ energy levels were observed between deuteron energies of 2.4 and 3.2 Mev. The Breit-Wigner single-level formula is used to extract resonance parameters for these levels.
