Cross sections for the radiative capture and one nucleon emission reactions have been obtained by mass identification of reaction products at 0° using thin targets for the systems ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ (70 and 59 MeV), ${}_{}{}^{30}{}_{}{}^{}\mathrm{Si}$ + ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ (70 and 59 MeV) and ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$ + ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ (59 MeV). The cross sections for radiative capture are in all cases < 500 nb. The measurement of the ${}_{}{}^{30}{}_{}{}^{}\mathrm{Si}$ + ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ cross section is in disagreement with previous work performed using thick targets. This discrepancy is discussed.
