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 ...
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 (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 ...
Capture cross section measurements of (186,187,188)Os at n_TOF : the resolved resonance region
(EDP Sciences, 2008)
The neutron capture cross sections of (186,187,188)Os have been measured at the CERN neutron time-of-flight facility, n_TOF, in the neutron energy range from 1 eV up to 1 MeV. In this contribution, we report the results ...
Measurement of the radiative neutron capture cross section of Pb-206 and its astrophysical implications
(2007-10)
The (n,gamma) cross section of Pb-206 has been measured at the CERN n_TOF facility with high resolution in the energy range from 1 eV to 620 keV by using two optimized C6D6 detectors. In the investigated energy interval ...
Neutron capture cross section of Th-232 measured at the n_TOF facility at CERN in the unresolved resonance region up to 1 MeV
(2006-05)
We have measured the neutron capture reaction yield of Th-232 at the neutron time-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The average capture cross section has been extracted in the energy ...
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, ...
