The C(Li, He) N reactions were measured at E (Li) = 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 N proton spectroscopic factors were extracted to be 0.67±0.09 and 0.73±0.10 , respectively. Using the C( p, γ) N direct capture S( 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 C( p, γ) N S( E) factors and reaction rates were determined at stellar energies. The present work offers an independent examination to the existing results of the C( p, γ) N reaction. [ABSTRACT FROM AUTHOR]
