The neutron time-of-flight facility n-TOF at CERN: Phase II
(AIP Publishing, 2011)
Neutron-induced reactions are studied at the neutron time-of-flight facility n-TOF at CERN. The facility uses 6∼ns wide pulses of 20 GeV/c protons impinging on a lead spallation target. The large neutron energy range and ...

Is a global coupled-channel dispersive optical model potential for actinides feasible?
(American Physical Society, 2005-12-01)
An isospin-dependent coupled-channel optical model potential containing a dispersive term with a nonlocal contribution is used to simultaneously fit the available experimental database (including strength functions and ...

197Au(n,γ) cross section in the unresolved resonance region
(American Physical Society, 2011)
The cross section of the reaction 197Au(n,γ) 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 C 6D6 ...

Neutron capture cross sections for the Re/Os clock
(AIP Publishing, 2005)
The radioactive decay of 187Re → 187Os (t 1/2 = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the 187Os abundance is the difference between the natural abundance ...

Description of analyzing power and (p,n) reaction by a global dispersive coupled-channel optical model potential
(AIP Publishing, 2010)
A global dispersive coupled-channel optical model potential is used to analyze the proton elastic/inelastic analyzing power data and (p,n) data in order to investigate the prediction power of this potential. The numerical ...

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 ...
