Angular distributions for the 7^Li（6^Li, 7^Li）6^Li elastic-transfer reaction have been measured with the Q3D magnetic spectrograph at the HI-13 tandem accelerator of Beijing, China. The neutron spectroscopic factors of 7^Li are derived by comparing the calculated differential cross sections, which are obtained through the distorted-wave Born approximation （DWBA） calculation, to the experimental data. And these spectroscopic factors are then used to deduce the direct capture cross sections in 6^Li（n, γ）TLi at energies of astrophysical relevance.
The radiative capture reaction plays an important role in nuclear astrophysics. We have indirectly measured the astrophysical S（E） factors for some proton capture reactions and reaction rates for several neutron capture reactions with one nucleon transfer reactions at HI-13 tandem accelerator in recent years. Some of them are compiled into IAEA EXFOR database and JINA REACLIB project, and used in the network calculations of Big Bang nucleosynthesis and type-I X-ray bursts.
