中文摘要：

Angular distributions for the ~7(Li)(~6(Li),~7(Li))~6(Li) 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 7Li 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 6Li(n,γ)7 Li at energies of astrophysical relevance.

英文摘要：

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.
