Abstract.

The cross-section of 8 Li(\(\alpha \),n)11 B has been measured at \(E_{\rm cm}\) = 1.25 MeV to be \(\sigma (E) = 500\) mb using novel techniques, i.e. a 8 Li radioactive ion beam produced at the tandem in Catania in combination with a 4 He gas cell and a \(4\pi \) neutron detector. The value is in fair agreement with previous work strengthening the model of inhomogeneous Big Bang nucleosynthesis.
