Neutron physics of the Re/Os clock. I : Measurement of the (n, gamma) cross sections of Os-186,Os-187,Os-188 at the CERN n_TOF facility
(2010-07-15)
The precise determination of the neutron capture cross sections of Os-186 and Os-187 is important to define the s-process abundance of Os-187 at the formation of the solar system. This quantity can be used to evaluate the ...
Neutron physics of the Re/Os clock. III : Resonance analyses and stellar (n, gamma) cross sections of Os-186,Os-187,Os-188
(2010-07-15)
Neutron resonance analyses have been performed for the capture cross sections of Os-186, Os-187, and Os-188 measured at the n_TOF facility at CERN. Resonance parameters have been extracted up to 5, 3, and 8 keV, respectively, ...
The Zr-92(n,gamma) reaction and its implications for stellar nucleosynthesis
(2010-05)
Because the relatively small neutron capture cross sections of the zirconium isotopes are difficult to measure, the results of previous measurements are often not adequate for a number of problems in astrophysics and nuclear ...
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 ...
