Au-197(n,gamma) cross section in the resonance region
(2010-04)
The (n,gamma) cross section of Au-197 has been measured at n_TOF in the resolved resonance region, up to 5 keV, with the aim of improving the accuracy in an energy range where it is not yet considered standard. The ...
Measurements of high-energy neutron-induced fission of (nat)Pb and (209)Bi
(EDP Sciences, 2010)
The CERN Neutron Time-Of-Flight (n_TOF) facility is well suited to measure low cross sections as those of neutron-induced fission in subactinides. The cross section ratios of (nat)Pb and (209)Bi relative to (235)U and ...
Neutron cross-sections for next generation reactors : New data from n_TOF
(2010)
In 2002, an innovative neutron time-of-flight facility started operation at CERN: n_TOF. The main characteristics that make the new facility unique are the high instantaneous neutron flux, high resolution and wide energy ...
High-accuracy U-233(n, f) cross-section measurement at the white-neutron source n_TOF from near-thermal to 1 MeV neutron energy
(2009-10)
The U-233(n, f) cross section has been measured at the white neutron source n_TOF in a wide energy range with a dedicated fission ionization chamber. We report here the results from similar to 30 meV to 1 MeV neutron energy. ...
The n_TOF Total Absorption Calorimeter for neutron capture measurements at CERN
(2009-09-21)
The n_TOF Collaboration has built and commissioned a high-performance detector for (n, gamma) measurements called the Total Absorption Calorimeter (TAC). The TAC was especially designed for measuring neutron capture ...
n_TOF Experiment: Past, Present And Future
(American Institute of Physics (AIP), 2009)
The neutron Time-of-Flight facility at CERN was built to measure the neutron capture and fission cross sections. A short description of the facility, the detectors and the data analysis techniques will be illustrated. A ...
Fission Cross-Section Measurements On (233)U And Minor Actinides At The CERN n_TOF Facility
(American Institute of Physics (AIP), 2009)
Neutron-induced fission cross-sections of minor actinides have been measured at the white neutron source n_TOF at CERN, Geneva. The studied isotopes include (233)U, interesting for Th/U based nuclear fuel cycles, (241,243)Am ...
Experimental study of the (91)Zr(n, gamma) reaction up to 26 keV
(2008-10)
The neutron capture cross sections of the Zr isotopes are relevant to studies in nuclear structure, nuclear astrophysics, and nuclear technology. The valence neutron of (91)Zr with respect to the neutron magic nucleus ...
Measurement of the (90,91,92,93,94,96)Zr(n,gamma) and (139)La(n,gamma) cross sections at n_TOF
(EDP Sciences, 2008-06)
Neutron capture cross sections of Zr and La isotopes have important implications in the field of nuclear astrophysics as well as in the nuclear technology. In particular the Zr isotopes play a key role for the determination ...
Neutron capture cross section of (90)Zr : Bottleneck in the s-process reaction flow
(2008-03)
The neutron capture cross sections of the Zr isotopes have important implications in nuclear astrophysics and for reactor design. The small cross section of the neutron magic nucleus (90)Zr, which accounts for more than ...
