U. ; IRFU, Saclay) ; Balibrea-Correa, J (Valencia U., IFIC) ; Barbagallo, M (CERN ; INFN, Bari) ; Bennett, S (Manchester U.) et al.
Radiative neutron capture cross section measurements are of fundamental importance for the study of the slow neutron capture (s-) process of nucleosynthesis. This mechanism is responsible for the formation of most elements heavier than iron in the Universe. [...]

Neutron capture cross sections are one of the fundamental nuclear data in the study of the s (slow) process of nucleosynthesis. More interestingly, the competition between the capture and the decay rates in some unstable nuclei determines the local isotopic abundance pattern. [...]

A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
/ Bacak, M (CERN ; TU Vienna ; IRFU, Saclay) ; Aïche, M (CENBG, Gradignan) ; Bélier, G (CEA DAM) ; Berthoumieux, E (IRFU, Saclay) ; Diakaki, M (IRFU, Saclay) ; Dupont, E (IRFU, Saclay) ; Gunsing, F (IRFU, Saclay ; CERN) ; Heyse, J (Euratom, Geel) ; Kopecky, S (Euratom, Geel) ; Laurent, B (CEA DAM) et al.
In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called $fission-tagging$ or $fission-veto technique$. For this purpose a new compact and fast fission chamber has been developed. [...]

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. [...]

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. [...]

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. [...]
