Measurement of the Ge 70 (n,γ) cross section up to 300 keV at the CERN n-TOF facility
(2019-10-17)
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 Ge70, which ...
Measurement of the 235U(n, f) cross section relative to the 6Li(n, t) and 10B(n, α) standards from thermal to 170 keV neutron energy range at n_TOF
(2019-07-01)
The 235U(n, f) cross section was measured at n_TOF relative to 6Li(n, t) and 10B(n,α) , with high resolution (L= 183. 49 (2) m) and in a wide energy range (25meV-170keV) with 1.5% systematic uncertainty, making use of a ...
Measurement of 73 Ge(n,γ) cross sections and implications for stellar nucleosynthesis
(2019-03-10)
73 Ge(n,γ) cross sections were measured at the neutron time-of-flight facility n_TOF at CERN up to neutron energies of 300 keV, providing for the first time experimental data above 8 keV. Results indicate that the stellar ...
First Measurement of 72Ge(n, γ) at n-TOF
(2018-06-29)
The slow neutron capture process (s-process) is responsible for producing about half of the elemental abundances heavier than iron in the universe. Neutron capture cross sections on stable isotopes are a key nuclear physics ...
Experimental setup and procedure for the measurement of the 7Be(n,p)7Li reaction at n_TOF
(2018-04-11)
Following the completion of the second neutron beam line and the related experimental area (EAR2) at the n_TOF spallation neutron source at CERN, several experiments were planned and performed. The high instantaneous neutron ...
The Nuclear Astrophysics program at n-TOF (CERN)
(EDP Sciences, 2017-12-30)
An important experimental program on Nuclear Astrophysics is being carried out at the n-TOF since several years, in order to address the still open issues in stellar and primordial nucleosynthesis. Several neutron capture ...
High-accuracy determination of the neutron flux in the new experimental area n_TOF-EAR2 at CERN
(2017-10-27)
A new high flux experimental area has recently become operational at the n_TOF facility at CERN. This new measuring station, n_TOF-EAR2, is placed at the end of a vertical beam line at a distance of approximately 20m from ...
The measurement programme at the neutron time-of-flight facility n-TOF at CERN
(EDP Sciences, 2017-09-13)
Neutron-induced reaction cross sections are important for a wide variety of research fields ranging from the study of nuclear level densities, nucleosynthesis to applications of nuclear technology like design, and criticality ...
Monte carlo simulations of the n-TOF lead spallation target with the Geant4 toolkit : A benchmark study
(EDP Sciences, 2017-09-13)
Monte Carlo (MC) simulations are an essential tool to determine fundamental features of a neutron beam, such as the neutron flux or the γ-ray background, that sometimes can not be measured or at least not in every position ...
High accuracy 234U(n,f) cross section in the resonance energy region
(EDP Sciences, 2017-09-13)
New results are presented of the 234U neutron-induced fission cross section, obtained with high accuracy in the resonance region by means of two methods using the 235U(n,f) as reference. The recent evaluation of the 235U(n,f) ...
