Description

The 13C(7Li, 6He) 14 N0,1 reactions were measured at E (7Li) = 34 MeV with the Q3D magnetic spectrometer of the HI-13 tandem accelerator, and the first peaks of the angular distributions were obtained for the first time. The 14N0,1 proton spectroscopic factors were extracted to be 0.67±0.09 and 0.73±0.10, respectively. Using the 13C(p, γ) 14N direct capture Sdc(E) factors derived by the spectroscopic factors, the direct measurement data for both 1- and 0- resonances were well fitted via updating the resonance parameters, and then the total astrophysical 13C(p, γ) 14N S(E) factors and reaction rates were determined at stellar energies. The present work offers an independent examination to the existing results of the 13 C(p, γ) 14N reaction. (orig.)
