The s-process in the Nd-Pm-Sm region: Neutron activation of 147Pm
(Elsevier: SCOAP3, 2019)
The Nd-Pm-Sm branching is of interest for the study of the s-process, related to the production of heavy elements in stars. As 148Sm and 150Sm are s-only isotopes, the understanding of the branching allows constraining the ...

Neutron cross-sections for advanced nuclear systems: the n_TOF project at CERN
(EDP Sciences, 2014)
The study of neutron-induced reactions is of high relevance in a wide variety of fields, ranging from stellar nucleosynthesis and fundamental nuclear physics to applications of nuclear technology. In nuclear energy, high ...

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 ...

Preparation and characterization of 33-S samples for 33-S(n,alpha)30-Si cross-section measurements at the n_TOF facility at CERN
(Elsevier, 2018-02-15)
Thin 33S samples for the study of the 33S(n,a)30Si cross-section at the n_TOF facility at CERN were made by thermal evaporation of 33S powder onto a dedicated substrate made of kapton covered with thin layers of copper, ...

Angular distribution in the neutron-induced fission of actinides
(EDP Sciences, 2013)
Above 1 MeV of incident neutron energy the fission fragment angular distribution (FFAD) has generally a strong anisotropic behavior due to the combination of the incident orbital momentum and the intrinsic spin of the ...

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 ...

The new vertical neutron beam line at the CERN n_TOF facility design and outlook on the performance
(Elsevier, 2015)
At the neutron time-of-flight facility n_TOF at CERN a new vertical beam line was constructed in 2014, in order to extend the experimental possibilities at this facility to an even wider range of challenging cross-section ...

Saturation of coupling of collective levels in optical model calculations of even-even actinides
(EDP Sciences, 2017)
Saturation of the coupling-scheme is studied in dispersive optical model calculations of nucleon induced reactions on 238U target. Recently derived potential that is based on a soft-rotator-model (SRM) description of the ...
