Manchester (main) ; Seville U.) ; Aberle, O (CERN) ; Andrzejewski, J ; Audouin, L ; Bacak, M (CERN ; TU Vienna ; IRFU, Saclay) ; Balibrea, J ; Barbagallo, M ; Bečvář, F ; Berthoumieux, E ; Billowes, J et al. The CERN n_TOF neutron beam facility is characterized by a very high instantaneous neutron flux, excellent TOF resolution at the 185 m long flight path (EAR-1), low intrinsic background and coverage of a wide range of neutron energies, from thermal to a few GeV. These characteristics provide a unique possibility to perform high-accuracy measurements of neutron-induced reaction cross-sections and angular distributions of interest for fundamental and applied Nuclear Physics.

 $^7 \text{Be(n,} \alpha)$ and $^7 \text{Be(n,p)}$ cross-section measurement for the cosmological lithium problem at the n_TOF facility at CERN / Barbagallo, M (CERN) ; Colonna, N ; Aberle, O (CERN) ; Andrzejewski, J ; Audouin, L ; Bécares, V ; Bacak, M ; Balibrea, J ; Barros, S ; Bečvář, F et al. /n_TOF The Cosmological Lithium Problem refers to the large discrepancy between the abundance of primordial $^7$Li predicted by the standard theory of Big Bang Nucleosynthesis and the value inferred from the so-called “Spite plateau” in halo stars. A possible explanation for this longstanding puzzle in Nuclear Astrophysics is related to the incorrect estimation of the destruction rate of $^7$Be, which is responsible for the production of 95% of primordial Lithium.
