Abstract The angular distribution of the ²H(⁸Li, ⁹Be)_n (ground state) reaction, important to primordial nucleosynthesis in the inhomogeneous model, has been measured at E_c.m=8.1MeV using a secondary ⁸Li beam. Cross section of this reaction was determined to be 9.0±3.4mb. According to the cross section, the astrophysical S-factor was calculated to be 272±103keV b. It is shown that ²H(⁸Li, ⁹Be)_n (ground state) reaction is important for creating ⁹Be, but less important for destroying ⁸Li in primordial nucleosynthesis.
