Development of an Ionization Chamber for the Measurement of the$^{16}$ O(n, ${\alpha }$ )$^{13}$ C Cross-Section at the CERN n_TOF Facility / Urlass, Sebastian (TU, Dresden (main) ; HZDR, Dresden ; CERN) ; Junghans, Arnd R (HZDR, Dresden ; CERN) ; Hartmann, Andreas (HZDR, Dresden) ; Mingrone, Federica (CERN) ; Sobiella, Manfred (HZDR, Dresden) ; Stach, Daniel (HZDR, Dresden) ; Tassan-Got, Laurent (CERN) ; Weinberger, David (HZDR, Dresden) /n_TOF Collaboration
The$^{16}$ O(n,  ${\alpha }$ )$^{13}$ C reaction, as the inverse reaction of the astrophysically important$^{13}$ C( ${\alpha }$ , n)$^{16}$ O reaction, is proposed to be measured at the neutron time-of-flight (n_TOF) facility of CERN. To this purpose, a Double Frisch Grid Ionization Chamber (DFGIC) containing the oxygen atoms as a component in the counting gas has been developed and a prototype was constructed at Helmholtz-Zentrum Dresden-Rossendorf(HZDR), in Germany.

$^{7}$ Be(n,p)$^{7}$ Li Cross Section Measurement for the Cosmological Lithium Problem at the n $\_$ TOF Facility at CERN / n_TOF Collaboration
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 (Asplund et al. in Astrophys J 644:229–259, 2006, [1]), and the one predicted by Big Bang Nucleosynthesis (BBN).

Data for the s Process from n_TOF / n_TOF Collaboration
A considerable amount of (n, $\gamma $ ) reactions has been studied, so far, at the neutron time-of-flight facility n_TOF at CERN. The experimental program aims at determining and improving cross sections for a number of isotopes relevant to s-process nucleosynthesis. [...]

Measurement of the $^{244}$ Cm and $^{246}$ Cm Neutron-Induced Cross Sections at the n_TOF Facility / Alcayne, V (Madrid, CIEMAT) ; Kimura, A (JAERI, Tokai) ; Mendoza, E (Madrid, CIEMAT) ; Cano-Ott, D (Madrid, CIEMAT) ; Aberle, O (CERN) ; Amaducci, S (INFN, Catania) ; Andrzejewski, J (Lodz U.) ; Audouin, L (Orsay, IPN) ; Babiano-Suarez, V (Valencia U., IFIC) ; Bacak, M (CERN ; Vienna, Tech. U.) et al.
The neutron capture reactions of the$^{244}$ Cm and$^{246}$ Cm isotopes open the path for the formation of heavier Cm isotopes and of heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes belong to the minor actinides with a large contribution to the decay heat and to the neutron emission in irradiated fuels proposed for the transmutation of nuclear waste and fast critical reactors.

Exploring neutron channel solutions at CERN/n_TOF for the Cosmological Lithium Problem / Mengoni, A (ENEA, Bologna ; INFN, Bologna) ; Damone, L A (INFN, Bari ; Bari U.) ; Barbagallo, M (INFN, Bari ; CERN) ; Mastromarco, M (INFN, Bari ; CERN) ; Cosentino, L (INFN, Catania) ; Kappeler, F (KIT, Karlsruhe, IKP) ; Colonna, N (INFN, Bari) ; Finocchiaro, P (INFN, Catania) /n_TOF Collaboration
New measurements of the $^7$Be$(n, \alpha)$ $^4$He and $^7$Be$(n, p)$ $^7$Li reaction cross sections from thermal to keV neutron energies have been performed at CERN/n TOF. High purity $^7$Be material was produced at the Paul Scherrer Institute (PSI) and implanted at CERN/ISOLDE, demonstrating the feasibility of neutron measurements on samples produced at radioactive beam facilities.
