Excitation functions of deuterons from the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d){}_{}{}^{13}{}_{}{}^{}\mathrm{N}$ reaction over the bombarding-energy range 12-19 MeV were measured at several angles for the ground-state deuterons and at a laboratory angle of 40° for deuterons leading to the ground state, to the first excited state, and to the unresolved second and third excited states. Detailed angular distributions were measured at 16, 17, and 18 MeV for the ground state through the third excited state and at 19 MeV for the ground state through the seventh excited state. The ground-state angular distributions were analyzed with the conventional distorted-wave Born approximation. For the excited states, all of which are unstable with respect to proton decay, a number of alternative methods of calculation were attempted and the results were compared.
