主　　题：transfer reaction elastic scattering angular distribution 

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.
