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