Neutron capture on Zr-94 : Resonance parameters and Maxwellian-averaged cross sections
(2011-07-15)
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 ...
Au-197(n,gamma) cross section in the unresolved resonance region
(2011-03-17)
The cross section of the reaction Au-197(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 C6D6 ...
The Neutron Time-Of-Flight Facility n_TOF At CERN: Phase II
(American Institute of Physics (AIP), 2011)
Neutron-induced reactions are studied at the neutron time-of-flight facility n_TOF at CERN. The facility uses 6 similar to ns wide pulses of 20 GeV/c protons impinging on a lead spallation target. The large neutron energy ...
Astrophysics at n_TOF Facility at CERN
(IOP Publishing Ltd., 2011)
The neutron time of flight (n_TOF) facility at CERN is a spallation neutron source with white neutron energy spectrum (from thermal to several GeV), covering the full energy range of interest for nuclear astrophysics, in ...
Neutron-induced fission cross-section of U-233 in the energy range 0.5 <E-n <20 MeV
(2011-01)
The neutron-induced fission cross-section of U-233 has been measured at the CERN n_TOF facility relative to the standard fission cross-section of U-235 between 0.5 and 20MeV. The experiment was performed with a fast ...
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 ...
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 ...
