Measurement of the 70Ge(n,γ) cross section up to 300 keV at the CERN n_TOF facility
(American Physical Society, 2019)
Neutron capture data on intermediate mass nuclei are of key importance to nucleosynthesis in the weak component of the slow neutron capture processes, which occurs in massive stars. The (n,γ) cross section on 70Ge, which ...

238U(n, γ) reaction cross section measurement with C6D6 detectors at the n_TOF CERN facility
(EDP Sciences, 2014)
The radiative capture cross section of 238U is very important for the developing of new reactor technologies and the safety of existing ones. Here the preliminary results of the 238U(n,γ) cross section measurement performed ...

Current quests in nucleosynthesis: present and future neutron-induced reaction measurements
(EDP sciences, 2014)
We present some open questions in nucleosynthesis focused on the measurement of relevant neutron capture cross-sections and on new experimental methods. We review the recent 63Ni(n,γ) experiment carried out at the n_TOF ...

Measurement of the angular distribution of fission fragments using a PPAC assembly at CERN n-TOF
(Elsevier, 2014)
A fission reaction chamber based on Parallel Plate Avalanche Counters (PPACs) was built for measuring angular distributions of fragments emitted in neutron-induced fission of actinides at the neutron beam available at the ...

Measurement of the α ratio and (n, γ) cross section of 235U from 0.2 to 200 eV at n_TOF
(American Physical Society, 2020)
We measured the neutron capture-to-fission cross-section ratio (α ratio) and the capture cross section of 235U between 0.2 and 200 eV at the n_TOF facility at CERN. The simultaneous measurement of neutron-induced capture ...

Performance of the neutron time-of-flight facility n_TOF at CERN
(Springer Verlag, 2013)
The neutron time-of-flight facility n_TOF features a white neutron source produced by spallation through 20 GeV/c protons impinging on a lead target. The facility, aiming primarily at the measurement of neutron-induced ...

Measurement of the neutron capture cross section of the fissile isotope 235U with the CERN n-TOF total absorption calorimeter and a fission tagging based on micromegas detectors
(EDP Sciences, 2017)
The accuracy on neutron capture cross section of fissile isotopes must be improved for the design of future nuclear systems such as Gen-IV reactors and Accelerator Driven Systems. The High Priority Request List of the ...

Measurement and analysis of the 241Am(n,γ ) cross section with liquid scintillator detectors using time-of-flight spectroscopy at the n_TOF facility at CERN
(American Physical Society, 2014)
The 241Am(n,γ ) cross section has been measured at the n_TOF facility at CERN using deuterated benzene liquid scintillators, commonly known as C6D6 detectors, and time-of-flight spectrometry. The results in the ...

Experimental setup and procedure for the measurement of the 7Be(n,α)α reaction at n_TOF
(Elsevier, 2016-09-11)
The newly built second experimental area EAR2 of the n_TOF spallation neutron source at CERN allows to perform (n, charged particles) experiments on short-lived highly radioactive targets. This paper describes a detection ...

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 ...
