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 ...
Measurement of the neutron induced fission cross section on transuranic (TRU) elements at the n_TOF facility at CERN
(American Institute of Physics (AIP), 2007)
During the 2004 campaign, the n_TOF collaboration measured neutron fission cross sections for U-233, Am-241,Am-243, Cm-245, as well as the fission standards U-235.238, using a sealed Fission Ionization Chamber (FIC). The ...
The role of fission in the r-process
(Elsevier, 2007)
We have developed a full set of fission rates that include spontaneous fission, neutron-induced fission, beta-delayed fission and, neutrino-induced fission, that are supplemented with realistic distributions of fission ...
Production of intermediate-mass and heavy nuclei
(Elsevier, 2007)
Nucleosynthesis is the science related to all astrophysical processes which are responsible for the abundances of the elements and their isotopes in the universe. The astrophysical sites are the big bang and stellar objects. ...
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 ...
Measurements of neutron capture cross-sections at n_TOF
(American Institute of Physics (AIP), 2007)
Capture cross-sections on isotopes relevant to accelerator driven systems for energy production and nuclear waste transmutation, and to stellar nucleosynthesis have been studied at the innovative neutron time of flight ...
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 ...
Cross section predictions for hydrostatic and explosive burning
(2006-10-17)
We review different models used for reactions involved in nuclear astrophysics. The reaction rate is defined for resonant as well as for non-resonant processes. For low-density nuclei, we describe the DWBA method, the ...
alpha-induced cross sections of Cd-106 for the astrophysical p process
(2006-08)
The Cd-106(alpha,gamma)Sn-110 reaction cross section has been measured in the energy range of the Gamow window for the astrophysical p-process scenario. The cross sections for Cd-106(alpha,n)Sn-109 and for Cd-106(alpha,p)In-109 ...
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 ...
