The cross section of the 11B(n, α)8Li reaction has been measured at En = 7.6-12.6 MeV. The neutron beam was produced via the D(d,n)3He reaction and a BF3 detector was used both as a target and a detector for the delayed α-activity of 8Li. Using the principle of detailed balance the data were converted to the case of the 8Li(α,n0)11B reaction. The resulting astrophysical S(E) factor is dominated by a resonance at ER = 580 keV, with ΓR = 200 keV and S(ER) = 8400 MeVb. The significance of this result for the inhomogeneous Big Bang nucleosynthesis is discussed.
