Neutron induced reactions for the s process, and the case of Fe and Ni isotopes
(2012)
Neutron capture cross sections are the key nuclear physics input to understand nucleosynthesis of the slow neutron capture process (s process). At the neutron time of flight facility n-TOF at CERN neutron capture cross ...
Neutron measurements for advanced nuclear systems : The n_TOF project at CERN
(2011-12-15)
A few years ago, the neutron time-of-flight facility n_TOF was built at CERN to address some of the urgent needs of high-accuracy nuclear data for Accelerator Driven Systems and other advanced nuclear energy systems, as ...
Measurement of the neutron-induced fission cross-section of Am-243 relative to U-235 from 0.5 to 20 MeV
(2011-12)
The ratio of the neutron-induced fission cross-sections of Am-243 and U-235 was measured in the energy range from 0.5 to 20 MeV with uncertainties of approximate to 4%. The experiment was performed at the CERN n_TOF facility ...
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, ...
