Destruction of the cosmic γ -ray emitter Al 26 in massive stars: Study of the key Al 26 (n,p) reaction
(2021-08-30)
The Al26(n,p)Mg26 reaction is the key reaction impacting on the abundances of the cosmic γ-ray emitter Al26 produced in massive stars and impacts on the potential pollution of the early solar system with Al26 by asymptotic ...
Measurement of the α ratio and (n,γ) cross section of U 235 from 0.2 to 200 eV at n_TOF MEASUREMENT of the α RATIO and ... J. BALIBREA-CORREA et al.
(2020-10-20)
We measured the neutron capture-to-fission cross-section ratio (α ratio) and the capture cross section of U235 between 0.2 and 200 eV at the n_TOF facility at CERN. The simultaneous measurement of neutron-induced capture ...
Neutron Capture Cross Section of Unstable Ni-63 : Implications for Stellar Nucleosynthesis
(2013-01-08)
The Ni-63(n, gamma) 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 ...
Measurement of resolved resonances of Th-232(n, gamma) at the n_TOF facility at CERN
(2012-06-01)
The yield of the neutron capture reaction Th-232(n, gamma) has been measured at the neutron time-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The reduction of the acquired data to the capture ...
Neutron Capture Measurements on Minor Actinides at the n_TOF Facility at CERN : Past, Present and Future
(2011-08-11)
The successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear data libraries. Recent sensitivity studies and reports [1-3] have ...
Fission Cross-section Measurements of U-233, Cm-245 and Am-241,Am-243 at CERN n_TOF Facility
(2011-08-11)
Neutron-induced fission cross-sections of minor actinides have been measured using the n_TOF white neutron source at CERN. Geneva, as part of a large experimental program aiming at collecting new data relevant for nuclear ...
Np-237(n,f) Cross Section : New Data and Present Status
(2011-08-11)
In this document, we present the final result obtained at the n_TOF experiment; for the neutron-induced fission cross section of the Np-237, from the fission threshold up to 1 GeV. The method applied to get tins result is ...
High-energy Neutron-induced Fission Cross Sections of Natural Lead and Bismuth-209
(2011-08-11)
The CERN Neutron Time-Of-Flight (n_TOF) facility is well suited to measure small neutron-induced fission cross sections, as those of subactinides. The cross section ratios of (nat)Pb and (209)Bi relative to (235)U and ...
Au-197(n,gamma) cross section in the unresolved resonance region
(2011-03-17)
The cross section of the reaction Au-197(n,gamma) was measured with the time-of-flight technique at the n_TOF (neutron time-of-flight) facility in the unresolved resonance region between 5 and 400 keV using a pair of C6D6 ...
The Neutron Time-Of-Flight Facility n_TOF At CERN: Phase II
(American Institute of Physics (AIP), 2011)
Neutron-induced reactions are studied at the neutron time-of-flight facility n_TOF at CERN. The facility uses 6 similar to ns wide pulses of 20 GeV/c protons impinging on a lead spallation target. The large neutron energy ...
