Recent results in nuclear astrophysics at the n_TOF facility at CERN
(Sissa Medialab, 2016)
The neutron time of flight (n_TOF) facility at CERN is a spallation source characterized by a white neutron spectrum. The innovative features of the facility, in the two experimental areas, (20 m and 185 m), allow for an ...

The neutron time-of-flight facility n-TOF at CERN: Phase II
(AIP Publishing, 2011)
Neutron-induced reactions are studied at the neutron time-of-flight facility n-TOF at CERN. The facility uses 6∼ns wide pulses of 20 GeV/c protons impinging on a lead spallation target. The large neutron energy range and ...

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 ...

Description of analyzing power and (p,n) reaction by a global dispersive coupled-channel optical model potential
(AIP Publishing, 2010)
A global dispersive coupled-channel optical model potential is used to analyze the proton elastic/inelastic analyzing power data and (p,n) data in order to investigate the prediction power of this potential. The numerical ...

HiSPANoS facility and the new neutron beam line for TOF measurements at the Spanish National Accelerator Lab (CNA)
(Institute of Physics Publishing, 2020)
HiSPANoS (HiSPAlis Neutron Source) is the first accelerator-based neutron facility in Spain, installed at the Centro Nacional de Aceleradores (CNA), where different experiments have been performed related to nuclear ...

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 ...

Neutron capture cross section measurements at n_TOF of Np-237, Pu-240 and Am-243 for the transmutation of nuclear waste
(AIP Publishing, 2006)
Accurate and reliable neutron capture cross section data for actinides are necessary for the proper design, safety regulation and precise performance assessment of transmutation devices such as Fast Critical Reactors or ...

Measurement of La-139(n,gamma) cross section at n_TOF
(American Institute of Physics, 2006)
The capture cross section of the 139La has been measured relative to 197Au standard at n_TOF. We provide here a short description of the experimental apparatus and of the data analysis procedures. The extracted resonance ...
