Neutron capture cross section of unstable 63Ni: implications for stellar nucleosynthesis
(American Physical Society, 2013-01-08)
The 63Ni(n,γ) cross section has been measured for the first time at the neutron time-of-flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were ...

74 Ge(n, γ) cross section below 70 keV measured at n_TOF CERN
(Springer Nature, 2022)
Neutron capture reaction cross sections on 74Ge are of importance to determine 74Ge production during the astrophysical slow neutron capture process. We present new resonance data on 74Ge(n, γ) reactions below 70 keV neutron ...

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 ...

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 ...

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, ...
