摘　　要：The 13C（7Li, 6He）laN reaction is measured at E（TLi） = 34 MeV with the Q3D mag- netic spectrometer of HI-13 tandem accelerator. Angular distributions at forward angles for proton transfer to the ground and the first excited states in 14N are obtained. In addition, angular distri- bution for 7Li ＋ 13C elastic scattering is also measured. The optical potential parameters for the entrance and exit channels of the transfer reactions are derived by fitting the 7Li ＋ 13C and 6Li ＋ 14N elastic scattering experimental data, and their angular distributions are well reproduced by the distorted wave Born approximation calculations. A phase shift of about 2° between the calculations and the experiment data has been found in the earlier （TLi, 6He） study, whereas no such phase shift is observed in the present work.The 13C（7Li, 6He）laN reaction is measured at E（TLi） = 34 MeV with the Q3D mag- netic spectrometer of HI-13 tandem accelerator.
