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

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