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 ...

Cross section measurements of 155,157Gd(n, γ) induced by thermal and epithermal neutrons
(Springer Nature, 2019)
Neutron capture cross section measurements on 155Gd and 157Gd were performed using the time-of-flight technique at the n_TOF facility at CERN on isotopically enriched samples. The measurements were carried out in the n_TOF ...

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 ...

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 ...

Thermal (n, γ) cross section and resonance integral of 171Tm
(American Physical Society, 2019)
Background: About 50% of the heavy elements are produced in stars during the slow neutron capture process. The analysis of branching points allows us to set constraints on the temperature and the neutron density in ...

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 ...

Measurement of 208 Pb ( n , γ ) 209 Pb Maxwellian averaged neutron capture cross section
(American Physical Society, 2017)
The doubly magic 208Pb nucleus is a bottleneck at the termination of the s-process path due to its very low neutron capture cross section. This cross section is also important for the decomposition ofs,r processes and ...

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 ...

Measuring neutron capture rates on ILL-produced unstable isotopes (147Pm, 171Tm and 204Tl, and plans for 79Se and 163Ho) for nucleosynthesis studies
(EDP Sciences, 2018)
Neutron capture cross sections are among the main inputs for nucleosynthesis network calculations. Although well known for the majority of the stable isotopes, this quantity is still unknown for most of the unstable isotopes ...
