Radiative Capture of Protons byC13

Abstract

The reaction ${\mathrm{C}}^{13}(p,\gamma ){\mathrm{N}}^{14}$ has been studied experimentally for proton bombarding energies between 0.4 and 2.7 MeV. Targets of carbon enriched in the isotope ${\mathrm{C}}^{13}$ were prepared, and thick and thin target excitation functions obtained. Five resonances were found, corresponding to excited states of ${\mathrm{N}}^{14}$ at 8.05, 8.62, 8.70, 9.18, and 9.49 Mev. The radiation spectrum from these levels was found to involve several branches of decay and transitions cascading through intermediate levels.
