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, ...
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 ...
Measurement of the Sm-151(n,gamma)Sm-152 cross section at n_TOF
(2005-07-25)
The Sm-151(n,gamma) Sm-152 cross section, which is important for the interpretation of the Sm-151 branching as an s-process thermometer, was measured from 1 eV up to 1 MeV at the innovative n-TOF facility at CERN. Based ...
Neutron capture cross section measurements for nuclear astrophysics at CERN n_TOF
(2005-07-25)
A series of neutron capture cross section measurements of interest to nuclear astrophysics have been recently performed at n-TOF, the neutron spallation source operating at CERN. The low repetition frequency of the proton ...
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, ...
