Bund.) ; Lederer-Woods, C (Edinburgh U.) ; Tattersall, A (Edinburgh U.) ; Battino, U (Edinburgh U.) ; Gunsing, F (IRFU, Saclay ; CERN) ; Heinitz, S (PSI, Villigen) ; Lerendegui-Marco, J (Seville U.) ; Krtička, M (Charles U. ; Seville U.) ; Reifarth, R (Frankfurt U.) ; Valenta, S (Charles U.) et al.
The slow neutron capture process (s-process) is responsible for producing about half of the elemental abundances heavier than iron in the universe. Neutron capture cross sections on stable isotopes are a key nuclear physics input for s-process studies. [...]

/n_TOF
The neutron time of flight (n_TOF) facility at CERN is a spallation source characterized by a white neutron spectrum. The innovative features of the facility, in the two experimental areas, (20 m and 185 m), allow for an accurate determination of the neutron cross section for radioactive samples or for isotopes with small neutron capture cross section, of interest for Nuclear Astrophysics.

High-resolution cross section measurements for neutron interactions on $^{89}$Y with incident neutron energies up to 95 keV
/ Tagliente, G (INFN, Bari) ; Milazzo, P M (INFN, Trieste) ; Paradela, C (Geel, JRC) ; Kopecky, S (Geel, JRC) ; Vescovi, D (INFN, Perugia ; Cagliari Observ.) ; Alaerts, G (Geel, JRC) ; Damone, L A (INFN, Bari ; CERN) ; Heyse, J (Geel, JRC) ; Krtička, M (Charles U.) ; Schillebeeckx, P (Geel, JRC) et al.
The cross section of the $^{89}$Y(n, $\gamma $) reaction has important implications in nuclear astrophysics and for advanced nuclear technology. Given its neutron magic number N = 50 and a consequent small neutron capture cross section, $^{89}$Y represents one of the key nuclides for the stellar s-process. [...]

Detector set up for the measurements of the neutron-induced fission cross section of $^{235}$U relative to n-p scattering up to 150 MeV at CERN-n_TOF
/ Pirovano, E (Braunschweig, Phys. Tech. Bund.) ; Manna, A (INFN, Bologna ; U. Bologna, DIFA) ; Colonna, N (INFN, Bari) ; Console Camprini, P (INFN, Bologna ; ENEA, Bologna) ; Cosentino, L (INFN, LNS) ; Dietz, M (Braunschweig, Phys. Tech.

The measurement of the $^{235}$U(n,f) reaction cross section in the neutron energy region 10 MeV to 500 MeV was carried out at the CERN n_TOF facility. The experimental campaign, completed in 2018, provided precise and accurate data on the fission reaction relative to neutron-proton elastic scattering. [...]
