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-induced fission cross section of 234 U measured at the CERN n_TOF facility
(American Physical Society, 2014)
The neutron-induced fission cross section of 234U has been measured at the CERN n-TOF facility relative to the standard fission cross section of 235U from 20 keV to 1.4 MeV and of 238U from 1.4 to 200 MeV. A fast ionization ...

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 ...

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 ...

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 ...

Neutron physics of the Re/Os clock. III. Resonance analyses and stellar (n, γ) cross sections of 186, 187, 188Os
(The American Physical Society, 2010)
Neutron resonance analyses have been performed for the capture cross sections of 186Os, 187Os, and 188Os measured at the n-TOF facility at cern. Resonance parameters have been extracted up to 5, 3, and 8 keV, respectively, ...

The 92Zr(n,γ) reaction and its implications for stellar nucleosynthesis
(The American Physical Society, 2010)
Because the relatively small neutron capture cross sections of the zirconium isotopes are difficult to measure, the results of previous measurements are often not adequate for a number of problems in astrophysics and nuclear ...

Neutron-induced fission cross section of Np 237 in the keV to MeV range at the CERN n-TOF facility
(American Physical Society, 2016)
The neutron-induced fission cross section of 237 Np was experimentally determined at the high-resolution and high-intensity facility n TOF , at CERN, in the energy range 100 keV to 9 MeV, using the 235 U ( n,f ...
