Measurement of the 235 U(n,f) cross section at n_TOF from thermal to 170 keV / Amaducci, Simone ; Amaducci, S ; Aberle, O ; Andrzejewski, J ; Audouin, L ; Bacak, M ; Balibrea, J ; Barbagallo, M ; Bečvář, F ; Berthoumieux, E et al.
The $^{235}$U(n,f) cross section plays a key role for nuclear physics due to its widespread use as a standard reference for neutron cross section measurements and for neutron flux measurements. Recent experimental data of the fission cross section have suggested the presence of discrepancies around 6–8% with respect to the most used libraries, precisely in the range between 10 keV and 30 keV.

A Proton Recoil Telescope for the characterisation of the neutron beam at n_TOF / n_TOF Collaboration
The neutron induced fission cross section of $^{235}$U is extensively used as a reference for neutron fluence measurements in various applications. At intermediate energies, the $^{235}$U(n,f) cross section plays an important role also for fundamental nuclear physics. [...]

$^{155}, ^{157}$Gd neutron capture cross sections measured at n_TOF (CERN) / Mastromarco, M (INFN, Bologna) ; Castelluccio, D M (ENEA, Bologna) ; Clai, G (ENEA, Bologna) ; Manna, A (INFN, Bologna) ; Massimi, C (INFN, Bologna) ; Rocchi, F (ENEA, Bologna) /n_TOF Collaboration
The accurate knowledge of the neutron capture cross sections of  $^{155}$Gd and $^{157}$Gd plays an important in many fields of science. Despite of its importance, only few experimental data are available on these two isotopes in the low energy region. [...]

Status and perspectives of the neutron time-of-flight facility n_TOF at CERN / Mingrone, F (CERN) ; Massimi, C (Bologna U.) /n_TOF Collaboration
The neutron time-of-flight facility of CERN, called n_TOF, started its operation in 2001, and since then it plays a major role in the field of neutron cross-section measurements. The two beam-lines available provide an excellent combination of good energy resolution and high instantaneous neutron flux, combining the time-of-flight method with a powerful neutron spallation source.

n + $^7$Be Cross-Sections of Astrophysical Interest at the CERN n_TOF Facility / Mastromarco, Mario (CERN ; Manchester U.) ; Damone, Lucia Anna (INFN, Bari ; Bari U.) ; Barbagallo, Massimo (CERN ; INFN, Bari) /n_TOF Collaboration
One of the possible explanations of the so-called Cosmological Lithium Problem (CLIP), i.e., the large overestimate of the primordial$^7$Li abundance by the standard Big Bang Nucleosynthesis theory (BBN), is related to an incorrect underestimation of the 7 Be destruction rate by neutron-induced reactions. To verify this possibility, the n + $^7$Be reactions have been investigated at n_TOF (CERN) in a wide neutron energy range, taking advantage of the new high-flux experimental area (EAR2) and specifically developed experimental setups.

Review and new concepts for neutron-capture measurements of astrophysical interest / n_TOF Collaboration
The idea of slow-neutron capture nucleosynthesis formulated in 1957 triggered a tremendous experimental effort in different laboratories worldwide to measure the relevant nuclear physics input quantities, namely ($n,\gamma$) cross sections over the stellar temperature range (from few eV up to several hundred keV) for most of the isotopes involved from Fe up to Bi.

Measurement of the radiative capture cross section of the s-process branching points $^{204}$Tl and $^{171}$Tm at the n_TOF facility (CERN) / Casanovas, A (Barcelona, Polytechnic U.) ; Domingo-Pardo, C (Valencia U., IFIC) ; Guerrero, C (Seville U.) ; Lerendegui-Marco, J (Seville U.) ; Calviño, F (Barcelona, Polytechnic U.) ; Tarifeño-Saldivia, A (Barcelona, Polytechnic U.) ; Dressler, R (PSI, Villigen) ; Heinitz, S (PSI, Villigen) ; Kivel, N (PSI, Villigen) ; Quesada, J M (Seville U.) et al.
The neutron capture cross section of some unstable nuclei is especially relevant for s-process nucleosynthesis studies. This magnitude is crucial to determine the local abundance pattern, which can yield valuable information of the s-process stellar environment. [...]

$^7$Be(n,p) cross section measurement for the Cosmological Lithium Problem at the n_TOF facility at CERN / Anna, Damone Lucia (INFN, Bari) ; Colonna, N (INFN, Bari) ; Barbagallo, M (INFN, Bari ; CERN) ; Mastromarco, M (INFN, Bari) ; Andrzejewski, J (Lodz U.) ; Finocchiaro, P (INFN, LNS) ; Cosentino, L (INFN, LNS) /n_TOF
One of the most puzzling problems in Nuclear Astrophysics is the "Cosmological Lithium Problem", i.e the discrepancy between the primordial abundance of $^7$Li observed in metal poor halo stars [1], and the one predicted by Big Bang Nucleosynthesis (BBN). One of the reactions that could have an impact on the problem is $^7$Be(n,p)$^7$Li. [...]
