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 ...
Measurement of the U-236(n, f) cross section from 170 meV to 2 MeV at the CERN n_TOF facility
(2011-10-31)
The neutron-induced fission cross section of U-236 was measured at the neutron Time-of-Flight (n_TOF) facility at CERN relative to the standard U-235(n, f) cross section for neutron energies ranging from above thermal to ...
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 ...
Neutron-induced fission cross section of Pb-nat and Bi-209 from threshold to 1 GeV : An improved parametrization
(2011-04-28)
Neutron-induced fission cross sections for Pb-nat and Bi-209 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 ...
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 ...
The Np-237(n,f) cross section at the CERN n-TOF facility
(American Institute of Physics (AIP), 2011)
The Np-237(n,f) cross sections have been measured at the n-TOF facility relative to the U-235 and U-238 fission cross sections. The n-TOF spallation neutron source at CERN is characterized by a high intensity flux, an ...
