197Au(n,γ) cross section in the resonance region
(The American Physical Society, 2010)
The (n,γ) cross section of 197Au has been measured at n-TOF in the resolved resonance region, up to 5keV, with the aim of improving the accuracy in an energy range where it is not yet considered standard. The measurements ...

The CERN n_TOF facility: a unique tool for nuclear data measurement
(EDP Sciences, 2016)
The study of the resonant structures in neutron-nucleus cross-sections, and therefore of the compound-nucleus reaction mechanism, requires spectroscopic measurements to determine with high accuracy the energy of the neutron ...

Nucleon scattering on actinides using a dispersive optical model with extended couplings
(American Physical Society, 2016)
The Tamura coupling model [Rev. Mod. Phys. 37, 679 (1965)] has been extended to consider the coupling of additional low-lying rotational bands to the ground-state band. Rotational bands are built on vibrational ...

New measurement of the 242Pu(n,γ) cross section at n_TOF
(EDP Sciences, 2016)
The use of MOX fuel (mixed-oxide fuel made of UO2 and PuO2) in nuclear reactors allows substituting a large fraction of the enriched Uranium by Plutonium reprocessed from spent fuel. With the use of such new fuel composition ...

Description of nucleon scattering on 208Pb by a fully Lane-consistent dispersive spherical optical model potential
(EDP Sciences, 2017)
A fully Lane-consistent dispersive spherical optical potential is proposed to describe nucleon scattering interaction with doubly magic nucleus 208Pb up to 200 MeV. The experimental neutron total cross sections, elastically ...

Astrophysics at n-TOF facility
(American Institute of Physics, 2010)
Heavy elements with Z ≥ 30 are made by neutron capture reactions during stellar He burning and presumably in supernovae. This contribution deals mainly with the slow neutron capture (s) process which is responsible for ...

Maxwellian Neutron Spectrum generation and Stellar Cross-Section measurements: measurement of the Au-197(n,gamma) MACS
(IOP Publishing, 2018)
Maxwellian-averaged cross-sections (MACS) are needed as an input for the models of stellar s- and r-processes nucleosynthesis. MACS can be obtained from activation measurements, irradiating a sample with the neutron field ...

Measurement of the 240Pu(n,f) cross-section at the CERN n-TOF facility: First results from experimental area II (EAR-2)
(EDP Sciences, 2017)
The accurate knowledge of the neutron-induced fission cross-sections of actinides and other isotopes involved in the nuclear fuel cycle is essential for the design of advanced nuclear systems, such as Generation-IV nuclear ...

Performance of the reconstruction algorithms of the FIRST experiment pixel sensors vertex detector
(Elsevier, 2014)
Hadrontherapy treatments use charged particles (e.g. protons and carbon ions) to treat tumors. During a therapeutic treatment with carbon ions, the beam undergoes nuclear fragmentation processes giving rise to significant ...

Neutron capture on 94Zr: Resonance parameters and Maxwellian-averaged cross sections
(American Physical Society, 2011)
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 ...
