Neutron resonance spectroscopy at n_TOF at CERN
(EDP Sciences, 2008)
Neutron resonance spectroscopy plays an important role in the investigation of neutron induced reaction cross sections and nuclear structure in the MeV excitation range. Neutron time-of-flight facilities are the most used ...
Simultaneous measurement of the neutron capture and fission yields of (233)U
(EDP Sciences, 2008)
We have measured the neutron capture and fission cross section of 233 U at the neutron time-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV with high accuracy by using a high performance 4 pi BaF(2) ...
Improved lead and bismuth (n,gamma) cross sections and their astrophysical impact
(EDP Sciences, 2008)
A series of (n,gamma) neutron capture measurements on the lead isotopes and bismuth have been carried Out at the CERN n_TOF installation in the neutron energy range from 1 eV up to 1 MeV. At n_TOF, contaminations due to ...
Recent results at n_TOF and future perspectives
(American Institute of Physics (AIP), 2008)
The neutron Time-of-Flight facility at CERN has been used for a series of neutron capture and fission cross sections measurements. The facility, detectors and data analysis techniques are described, followed by a brief ...
The neutron capture cross sections of (237)Np(n,gamma) and (240)Pu(n,gamma) and its relevance in the transmutation of nuclear waste
(EDP Sciences, 2008)
Neutron capture cross sections of actinides are of great relevance for the Transmutation of Nuclear Waste in Accelerator Driven Systems (ADS) and Generation-IV reactors. The neutron capture cross sections of (237)Np and ...
Measurement of the (197)Au(n,gamma) cross section at n_TOF : towards a new standard
(EDP Sciences, 2008)
Two different detectors and techniques are employed at n_TOF facility, at CERN, to improve the accuracy of the neutron capture cross section of (197)Au(n,gamma): a total absorption calorimeter and a Set Of C(6)D(6). The ...
Measurement of neutron induced fission of (235)U, (233)U and (245)Cm with the FIC detector at the CERN n_TOF facility
(EDP Sciences, 2008)
A series of measurements of neutron induced fission cross section of various TRU isotopes have been performed at the CERN n_TOF spallation neutron facility, in the energy range from thermal to nearly 250 MeV. The experimental ...
Nuclear physics for the Re/Os clock
(2008-01)
Dating the age of the universe by the beta-decay of (187)Re (t(1/2) = 41.2 Gyr) requires the accurate assessment of the s-process reaction flow. The daughter nucleus (187)Os as well as its immediate s-only neighbor (186)Os ...
The measurement of the (206)Pb(n,gamma) cross section and stellar implications
(2008-01)
The neutron capture cross section of (206)Pb has been measured at the CERN n_TOF spectrometer using a setup of two C(6)D(6) detectors. In the energy interval from 1 eV to 600 keV the cross section is dominated by resonances, ...
The (234)U neutron capture cross section measurement at the n_TOF facility
(EDP Sciences, 2008)
The neutron capture cross-section of (234)U has been measured for energies from thermal up to the keV region in the neutron time-of-flight facility n_TOF, based on a spallation source located at CERN. A 4 pi BaF(2) array ...
