GEANT4 simulation of the neutron background of the C$_6$D$_6$ set-up for capture studies at n_TOF / n_TOF collaboration
The neutron sensitivity of the C$_6$D$_6$ detector setup used at n_TOF for capture measurements has been studied by means of detailed GEANT4 simulations. A realistic software replica of the entire n_TOF experimental hall, including the neutron beam line, sample, detector supports and the walls of the experimental area has been implemented in the simulations.

Technol.) ; Kivel, N (PSI, Villigen) ; Pignatari, M (Basel U.) et al.
The cross section of the $^{62}$Ni($n,\gamma$) reaction was measured with the time-of-flight technique at the neutron time-of-flight facility n_TOF at CERN. Capture kernels of 42 resonances were analyzed up to 200~keV neutron energy and Maxwellian averaged cross sections (MACS) from $kT=5-100$ keV were calculated. [...]

A new CVD Diamond Mosaic-Detector for (n,$\alpha$) Cross-Section Measurements at the n_TOF Experiment at CERN / n_TOF Collaboration
At the n_TOF experiment at CERN a dedicated single-crystal chemical vapor deposition (sCVD) Diamond Mosaic-Detector has been developed for (n,$\alpha$) cross-section measurements. The detector, characterized by an excellent time and energy resolution, consists of an array of 9 sCVD diamond diodes. [...]

$^{197}$Au($n,\gamma$) cross section in the unresolved resonance region / Lederer, C. (Vienna U.) ; Colonna, N (INFN, Bari) ; Domingo-Pardo, C (CSIC, Catalunya) ; Gunsing, F (DAPNIA, Saclay) ; Kappeler, F (Karlsruhe, Inst. Technol.) ; Massimi, C. (INFN, Bologna ; Bologna U.) ; Mengoni, A. (CERN ; IAEA, Vienna) ; Wallner, A. (Vienna U.) ; Abbondanno, U. (INFN, Trieste) ; Aerts, G. (DAPNIA, Saclay) et al.
The cross section of the reaction (197)Au(n,gamma) was measured with the time-of-flight technique at the n_TOF (neutron time-of-flight) facility in the unresolved resonance region between 5 and 400 keV using a pair of C(6)D(6) (where D denotes (2)H) liquid scintillators for the detection of prompt capture gamma rays. The results with a total uncertainty of 3.9%-6.7% for a resolution of 20 bins per energy decade show fair agreement with the Evaluated Nuclear Data File Version B-VII.0 (ENDF B-VII.0), which contains the standard evaluation.

Neutron capture on (94)Zr: Resonance parameters and Maxwellian-averaged cross sections / Tagliente, G (Gent U. ; INFN, Bari) ; Milazzo, P.M (INFN, Trieste) ; Fujii, K (INFN, Trieste) ; Abbondanno, U (INFN, Trieste) ; Aerts, G (DAPNIA, Saclay) ; Alvarez, H (Santiago de Compostela U.) ; Alvarez-Velarde, F (Madrid, CIEMAT) ; Andriamonje, S (DAPNIA, Saclay) ; Andrzejewski, J (Lodz U.) ; Audouin, L (Karlsruhe, Forschungszentrum) et al.
The neutron capture cross sections of the Zr isotopes play an important role in nucleosynthesis studies. The s-process reaction flow between the Fe seed and the heavier isotopes passes through the neutron magic nucleus (90)Zr and through (91,92,93,94)Zr, but only part of the flow extends to (96)Zr because of the branching point at (95)Zr.

The Role of Fe and Ni for S-process Nucleosynthesis and Innovative Nuclear Technologies / Giubrone, G (Valencia U., IFIC) ; Ventura, A (ENEA, Bologna, Italy.) ; Perkowski, J (Lodz U.) ; Andriamonje, S (CERN) ; Carrapico, C (ITN, Lisbon) ; Wallner, A (U. Vienna (main)) ; Vannini, G (INFN, Bologna ; Bologna U.) ; Quesada, J M (Seville U.) ; Lederer, C (U. Vienna (main)) ; Tarrio, D (Santiago de Compostela U.) et al.
The accurate measurement of neutron capture cross sections of all Fe and Ni isotopes is important for disentangling the contribution of the s-process and the r-process to the stellar nucleosynthesis of elements in the mass range 60 < A < 120. At the same time, Fe and Ni are important components of structural materials and improved neutron cross section data is relevant in the design of new nuclear systems. [...]
