Abstract

The cross section for the astrophysically important ${}^{13}N$ (p,γ $)^{14}$ O reaction has been measured directly with an intense (3× $10^{8}$ particles/s) and pure (>99%) 8.2-MeV ${}^{13}N$ radioactive ion beam. The average value, for the 5.8–8.2-MeV ${}^{13}N$ energy range, is 106(30) μb. The partial γ width of the resonance which occurs in this reaction at a center-of-mass energy of 0.545 MeV has been deduced to be 3.8(1.2) eV. It is compared with theoretical predictions and indirect determinations.
