Neutron capture cross sections for the Re/Os clock
(American Institute of Physics (AIP), 2005)
The radioactive decay of (187)Re -> (187)Os (t(1/2) = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the (187)Os abundance is the difference between the natural ...
Measurement of capture cross sections of 90,91,92,94,96Zr isotopes at n_TOF
(American Institute of Physics (AIP), 2005)
The neutron capture cross sections for Zr isotopes have important implications in nuclear technologies as well in the field of nuclear astrophysics. The innovative features of the n_TOF CERN facility allowed for an accurate ...
Measurements at n_TOF of the neutron capture cross section of minor actinides relevant to the nuclear waste transmutation
(American Institute of Physics (AIP), 2005)
Accurate and reliable neutron-capture cross-section data for actinides are necessary for the proper design, safety regulation, and precise performance assessment of transmutation devices such as Fast Critical Reactors or ...
Measurement of the Th-232 neutron capture cross section at the CERN n_TOF facility
(American Institute of Physics (AIP), 2005)
The use of a fuel cycle based on Th-232 can substantially reduce the radiotoxicity of the produced nuclear waste since the lower atomic and mass number of thorium results in a strongly suppressed build-up of the higher ...
Time-energy relation of the n_TOF neutron beam : energy standards revisited
(2004-10-21)
The accurate determination of neutron cross-sections as a function of the neutron energy at a time-of-flight facility requires a precise knowledge of the time-energy relation for the neutron beam. For the n-TOF neutron ...
Neutron capture cross section measurement of Sm-151 at the CERN neutron time of flight facility (n_TOF)
(2004-10-15)
The Sm-151(n,gamma)Sm-152 cross section has been measured at the spallation neutron facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The new facility combines excellent resolution in neutron time-of-flight, ...
A low-mass neutron flux monitor for the n_TOF facility at CERN
(2004-09)
A small-mass system has been developed for monitoring the flux of neutrons with energy up to 1 MeV at the new time-of-flight facility at CERN, n_TOF. The monitor is based on a thin Mylar foil with a Li-6 deposit, placed ...
New experimental validation of the pulse height weighting technique for capture cross-section measurements
(2004-04-01)
The accuracy of the pulse height weighting technique for the determination of neutron capture cross-sections is investigated. The technique is applied to measurements performed with C6D6 liquid scintillation detectors of ...
