Measurement and analysis of the Am 243 neutron capture cross section at the n-TOF facility at CERN
(2014-09-11)
Background: The design of new nuclear reactors and transmutation devices requires to reduce the present neutron cross section uncertainties of minor actinides. Purpose: Improvement of the Am243(n,γ) cross section uncertainty. ...
Neutron-induced fission cross section of U 234 measured at the CERN n-TOF facility
(2014-04-15)
The neutron-induced fission cross section of U234 has been measured at the CERN n-TOF facility relative to the standard fission cross section of U235 from 20 keV to 1.4 MeV and of U238 from 1.4 to 200 MeV. A fast ionization ...
Neutron physics of the Re/Os clock. I : Measurement of the (n, gamma) cross sections of Os-186,Os-187,Os-188 at the CERN n_TOF facility
(2010-07-15)
The precise determination of the neutron capture cross sections of Os-186 and Os-187 is important to define the s-process abundance of Os-187 at the formation of the solar system. This quantity can be used to evaluate the ...
Neutron physics of the Re/Os clock. III : Resonance analyses and stellar (n, gamma) cross sections of Os-186,Os-187,Os-188
(2010-07-15)
Neutron resonance analyses have been performed for the capture cross sections of Os-186, Os-187, and Os-188 measured at the n_TOF facility at CERN. Resonance parameters have been extracted up to 5, 3, and 8 keV, respectively, ...
n_TOF Experiment: Past, Present And Future
(American Institute of Physics (AIP), 2009)
The neutron Time-of-Flight facility at CERN was built to measure the neutron capture and fission cross sections. A short description of the facility, the detectors and the data analysis techniques will be illustrated. A ...
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 ...
Status and outlook of the neutron time-of-flight facility
(2007-08)
The neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight ...
Neutron reactions and nuclear cosmo-chronology
(Elsevier, 2007-07)
The beta-decay of Re-187 (t(1/2) = 42.3 Gyr) represents a suited cosmo-chronometer for the age of the r-process abundances, since the radiogenic part of the daughter isotope (OS)-O-187 is defined by the difference between ...
The La-139(n,gamma) cross section : Key for the onset of the s-process
(2007-03)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La-139 have been measured relative to Au-197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...
New measurement of neutron capture resonances in Bi-209
(2006-08)
The neutron capture cross section of Bi-209 has been measured at the CERN n_TOF facility by employing the pulse-height-weighting technique. Improvements over previous measurements are mainly because of an optimized detection ...
