Results of the $^{244}$Cm, $^{246}$Cm and $^{248}$Cm neutron-induced capture cross sections measurements at EAR1 and EAR2 of the n_TOF facility
/ nTOF Collaboration
Accurate neutron capture cross section data for minor actinides (MAs) are required to estimate the production and transmutation rates of MAs in light water reactors, critical fast reactors like Gen-IV systems, and other innovative reactor systems such as accelerator driven systems (ADS). In particular, 244Cm, 246Cm and 248Cm play a role in the transport, storage and transmutation of the nuclear waste of the current nuclear reactors, due to the contribution of these isotopes to the radiotoxicity, neutron emission, and decay heat in the spent nuclear fuel.

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.

A new measurement of the $^{235}$U(n,f) fission cross section was carried out at n_TOF. The experiment covered the neutron energy range from 10 MeV up to 500 MeV, and it used the 1H(n,n) cross section as normalization for the neutron fluence measurement. [...]

Characterization of a detector setup for the measurement of the $^{235}$U(n,f) cross section relative to n-p scattering up to 500 MeV at the n_TOF facility at CERN
/ Manna, A (U. Bologna, DIFA ; INFN, Bologna) ; Pirovano, E (Braunschweig, Phys. Tech. Bund.) ; Colonna, N (INFN, Bari) ; Castelluccio, D (ENEA, Bologna ; INFN, Bologna) ; Camprini, P Console (ENEA, Bologna ; INFN, Bologna) ; Cosentino, L (INFN, LNS) ; Dietz, M (Braunschweig, Phys. Tech. Bund.) ; Ducasse, Q (Braunschweig, Phys. Tech. Bund.) ; Finocchiaro, P (INFN, LNS) ; Naour, C Le (Orsay, IPN) et al.
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. [...]

New insights on fission of $^{235}$U induced by high energy neutrons
/ n_TOF Collaboration
The $^{235}$U(n,f) reaction cross section was measured relative to neutron-proton elastic scattering for the first time in the energy region from 10 MeV to 440 MeV at the CERN n_TOF facility, extending the upper limit of the only previous measurement in the literature by more than 200 MeV. [...]

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. [...]
