Determination of the N13(p,)14O reaction cross section using a N13 radioactive ion beam

The cross section for the astrophysically important 13N(p, γ) 14O reaction has been measured directly with an intense (3 × 108 particles/s) and pure (> 99%) 8.2-MeV 13N radioactive ion beam. The average value, for the 5.8-8.2-MeV 13N 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.SCOPUS: ar.j
