Present Status and Future Programs of the n_TOF Experiment
(EDP Sciences, 2012)
The neutron time-of-flight facility n_TOF at CERN, Switzerland, operational since 2001, delivers neutrons using the Proton Synchrotron (PS) 20 GeV/c proton beam impinging on a lead spallation target. The facility combines ...
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 ...
A CVD diamond detector for (n,alpha) cross section measurements
(SISSA, 2012-01)
In astrophysics, the determination of the optical alpha-nucleus potential for low alpha-particle energies, crucial in understanding the origin of the stable isotopes, has turned out to be a challenge. Theory still cannot ...
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 ...
Fission Cross-section Measurements of U-233, Cm-245 and Am-241,Am-243 at CERN n_TOF Facility
(2011-08-11)
Neutron-induced fission cross-sections of minor actinides have been measured using the n_TOF white neutron source at CERN. Geneva, as part of a large experimental program aiming at collecting new data relevant for nuclear ...
Study of Photon Strength Function of Actinides : the Case of U-235, Np-238 and Pu-241
(2011-08-11)
The decay from excited levels in medium and heavy nuclei can be described in a statistical approach by means of Photon Strength Functions and Level Density distributions. The study of electromagnetic cascades following ...
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 ...
