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 ...

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 ...

Simultaneous measurement of neutron-induced capture and fission reactions at CERN
(Springer Verlag, 2012)
The measurement of the capture cross-section of fissile elements, of utmost importance for the design of innovative nuclear reactors and the management of nuclear waste, faces particular difficulties related to the γ-ray ...

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, ...

Neutron physics of the Re/Os clock. I. Measurement of the (n, γ) cross sections of 186, 187, 188 Os at the CERN n_TOF facility
(The American Physical Society, 2010)
The precise determination of the neutron capture cross sections of 186Os and 187Os is important to define the s-process abundance of 187Os at the formation of the solar system. This quantity can be used to evaluate the ...

Neutron-induced fission cross section of 245 Cm: New results from data taken at the time-of-flight facility n_TOF
(American Physical Society, 2012)
The neutron-induced fission cross section of 245Cm was measured at n-TOF in a wide energy range and with high resolution. The energy dependence, measured in a single measurement from 30 meV to 1 MeV neutron energy, has ...
