96 Zr(n,γ) measurement at the n_TOF facility at CERN
(American Physical Society, 2011)
The (n,γ) cross section of 96Zr has been investigated at the CERN n-TOF spallation neutron source. High-resolution time-of-flight measurements using an enriched ZrO2 sample allowed us to analyze 15 resonances below 40 keV ...

Measurement of resolved resonances of 232Th(n, γ) at the n_TOF facility at CERN
(American Physical Society, 2012)
The yield of the neutron capture reaction 232Th(n,γ) has been measured at the neutron time-of-flight facility n-TOF at CERN in the energy range from 1 eV to 1 MeV. The reduction of the acquired data to the capture yield ...

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 ...

Extensions to the charge exchange recombination spectroscopy diagnostic suite at ASDEX Upgrade
(AIP Publishing, 2017)
A new core charge exchange recombination spectroscopy diagnostic has been installed in the ASDEX Upgrade tokamak that is capable of measuring the impurity ion temperature, toroidal rotation, and density on both the low ...

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 139 La(n ,γ) cross section: Key for the onset of the s -process
(The American Physical Society, 2007)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La139 have been measured relative to Au197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...

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 ...

Pedestal and Er profile evolution during an edge localized mode cycle at ASDEX Upgrade
(IOP Publishing, 2017)
The upgrade of the edge charge exchange recombination spectroscopy diagnostic at ASDEX Upgrade has enabled highly spatially resolved me asurements of the impurity ion dynamics during an edge-localized mode cycle ( E ...

Reaction dynamics induced by the radioactive ion beam 7Be on medium-mass and heavy targets
(American Institute of Physics, 2015)
We studied the reaction dynamics induced at Coulomb barrier energies by the weakly-bound Radioactive Ion Beam 7Be (Sα = 1.586 MeV) on medium-mass (58Ni) and heavy (208Pb) targets. The experiments were performed at INFN-LNL ...

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 ...
