Neutron capture and total cross-section measurements on $^{94,95,96}$Mo at n_TOF and GELINA
/ n_TOF Collaboration
Capture and total cross section measurements for 94,95,96Mo have been performed at the neutron time-of-flight facilities, n_TOF at CERN and GELINA at JRC-Geel. The measurements were performed using isotopically enriched samples with an enrichment above 95% for each of the 94,95,96Mo isotopes. [...]

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. [...]

Multi-section fission ionization chamber for measurement of 239Pu(n,γ) reaction in fission tagging method
/ Perkowski, J (Lodz U.) ; Alcayne, V (Madrid, CIEMAT) ; Andrzejewski, J (Lodz U.) ; Cano-Ott, D (Madrid, CIEMAT) ; Gawlik-Ramięga, A (Lodz U.) ; Mendoza, E (Madrid, CIEMAT) ; Sánchez-Caballero, A (Madrid, CIEMAT) ; Sibbens, G (Geel, JRC) ; Vanleeuw, D (Geel, JRC) ; Aberle, O (CERN) et al.
The 239Pu(n,γ) reaction cross section is very important for operation of both thermal and fast reactors, when loaded with MOX fuels. According to the NEA/OECD High Priority Request List the precision of cross section data for this reaction should be improved. [...]

Status report of the n_TOF facility after the 2nd CERN long shutdown period
/ Patronis, N (Ioannina U. ; CERN) ; Mengoni, A (ENEA, Bologna ; INFN, Bologna) ; Goula, S (Ioannina U.) ; Aberle, O (CERN) ; Alcayne, V (Madrid, CIEMAT) ; Altieri, S (INFN, Pavia ; Brescia U. ; Pavia U.) ; Amaducci, S (INFN, Catania) ; Andrzejewski, J (Lodz U.) ; Babiano-Suarez, V (Valencia U., IFIC) ; Bacak, M (CERN) et al.
During the second long shutdown period of the CERN accelerator complex (LS2, 2019-2021), several upgrade activities took place at the n_TOF facility. The most important have been the replacement of the spallation target with a next generation nitrogen-cooled lead target. [...]

Measurement of the $^{244}Cm$ and $^{246}Cm$ neutron-induced capture cross sections at the n_TOF facility
/ Alcayne, V (Madrid, CIEMAT) ; Kimura, A (JAERI, Tokai) ; Mendoza, E (Madrid, CIEMAT) ; Cano-Ott, D (Madrid, CIEMAT) ; Martínez, T (Madrid, CIEMAT) ; Aberle, O (CERN) ; Andrzejewski, J (Lodz U.) ; Audouin, L (Orsay, IPN) ; Bécares, V (Madrid, CIEMAT) ; Bacak, M (CERN ; IRFU, Saclay ; 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 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. [...]
