Abstract

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