New Measurement of Proton Transfer Reactions and Elastic Scattering for ⁷Li + ¹³C at 34 MeV

The ¹³C(⁷Li, ⁶He)¹⁴N reaction is measured at E(⁷Li) = 34 MeV with the Q3D magnetic 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 distribution 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 2o between the calculations and the experiment data has been found in the earlier (⁷Li, ⁶He) study, whereas no such phase shift is observed in the present work.
