摘要：

The cross section for the astrophysically important N-13 (p, gamma) O-14 reaction has been measured directly with an intense (3 x 10(8) particles/s) and pure (> 99%) 8.2-MeV N-13 radioactive ion beam. The average value, for the 5.8-8.2-MeV N-13 energy range, is 106(30) mu-b. The partial gamma-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.
