Neutron-induced fission cross section of Np237 in the keV to MeV range at the CERN n_TOF facility
/ Diakaki, M ; Karadimos, D ; Vlastou, R ; Kokkoris, M ; Demetriou, P ; Skordis, E ; Tsinganis, A ; Abbondanno, U ; Aerts, G ; Álvarez, H et al.
The neutron-induced fission cross section of Np237 was experimentally determined at the high-resolution and high-intensity facility n_TOF, at CERN, in the energy range 100 keV to 9 MeV, using the U235(n,f) and U238(n,f) cross section standards below and above 2 MeV, respectively. A fast ionization chamber was used in order to detect the fission fragments from the reactions and the targets were characterized as far as their mass and homogeneity are concerned by means of α spectroscopy and Rutherford backscattering spectroscopy respectively.

Santiago de Compostela (main)) ; Leong, L S (Orsay, IPN) ; Audouin, L (Orsay, IPN) ; Tassan-Got, L (Orsay, IPN) ; Praena, J (Seville U.) ; Berthier, B (Orsay, IPN) ; Ferrant, L (Orsay, IPN) et al.
We present the analysis of the resolved resonance region for the U-234(n,f) cross section data measured at the CERN n\_TOF facility. The resonance parameters in the energy range from 1 eV to 1500 eV have been obtained with the SAMMY code by using as initial parameters for the fit the resonance parameters of the JENDL-3.3 evaluation.

Neutron-induced fission cross section of U234 measured at the CERN n_TOF facility
/ Karadimos, D ; Vlastou, R ; Ioannidis, K ; Demetriou, P ; Diakaki, M ; Vlachoudis, V (CERN) ; Pavlopoulos, P ; Konovalov, V ; Abbondanno, U ; Aerts, G et al.
The neutron-induced fission cross section of U234 has been measured at the CERN n_TOF facility relative to the standard fission cross section of U235 from 20 keV to 1.4 MeV and of U238 from 1.4 to 200 MeV. A fast ionization chamber (FIC) was used as a fission fragment detector with a detection efficiency of no less than 97%. [...]

$^{197}$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-induced fission cross section of (nat)Pb and (209)Bi from threshold to 1 GeV: An improved parametrization
/ Tarrio, D (Santiago de Compostela U.) ; Tassan-Got, L (Orsay, IPN) ; Audouin, L (Orsay, IPN) ; Berthier, B (Orsay, IPN) ; Duran, I (Santiago de Compostela U.) ; Ferrant, L (Orsay, IPN) ; Isaev, S (Orsay, IPN) ; Le Naour, C (Orsay, IPN) ; Paradela, C (Santiago de Compostela U.) ; Stephan, C (Orsay, IPN) et al.
Neutron-induced fission cross sections for (nat)Pb and (209)Bi were measured with a white-spectrum neutron source at the CERN Neutron Time-of-Flight (n\_TOF) facility. The experiment, using neutrons from threshold up to 1 GeV, provides the first results for these nuclei above 200 MeV. [...]
