Experimental study of the (91)Zr(n, gamma) reaction up to 26 keV
(2008-10)
The neutron capture cross sections of the Zr isotopes are relevant to studies in nuclear structure, nuclear astrophysics, and nuclear technology. The valence neutron of (91)Zr with respect to the neutron magic nucleus ...
Neutron capture cross section of (90)Zr : Bottleneck in the s-process reaction flow
(2008-03)
The neutron capture cross sections of the Zr isotopes have important implications in nuclear astrophysics and for reactor design. The small cross section of the neutron magic nucleus (90)Zr, which accounts for more than ...
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 ...
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 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 ...
Measurement of the neutron capture cross section of the s-only isotope Pb-204 from 1 eV to 440 keV
(2007-01)
The neutron capture cross section of Pb-204 has been measured at the CERN n_TOF installation with high resolution in the energy range from 1 eV to 440 keV. An R-matrix analysis of the resolved resonance region, between 1 ...
Resonance capture cross section of Pb-207
(2006-11)
The radiative neutron capture cross section of Pb-207 has been measured at the CERN neutron time of flight installation n_TOF using the pulse height weighting technique in the resolved energy region. The measurement has ...
Measurement of the Sm-151(n, gamma) cross section from 0.6 eV to 1 MeV via the neutron time-of-flight technique at the CERN n_TOF facility
(2006-03)
The Sm-151(n,gamma) cross section was measured with the time-of-flight technique from 0.6 eV up to 1 MeV relative to the Au standard with an overall uncertainty of typically 6%. Neutrons were produced by spallation at the ...
