Neutron capture cross sections for the Re/Os clock
(AIP Publishing, 2005)
The radioactive decay of 187Re → 187Os (t 1/2 = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the 187Os abundance is the difference between the natural abundance ...

The 139 La(n ,γ) cross section: Key for the onset of the s -process
(The American Physical Society, 2007)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La139 have been measured relative to Au197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...

Measurement of La-139(n,gamma) cross section at n_TOF
(American Institute of Physics, 2006)
The capture cross section of the 139La has been measured relative to 197Au standard at n_TOF. We provide here a short description of the experimental apparatus and of the data analysis procedures. The extracted resonance ...

Neutron capture cross section of 90Zr: Bottleneck in the s-process reaction flow
(The American Physical Society, 2008)
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 90Zr, which accounts for more than 50% ...

High-accuracy U233 (n,f) cross-section measurement at the white-neutron source n_TOF from near-thermal to 1 MeV neutron energy
(The American Physical Society, 2009)
The 233U(n,f) cross section has been measured at the white neutron source n-TOF in a wide energy range with a dedicated fission ionization chamber. We report here the results from ∼30 meV to 1 MeV neutron energy. The ...

Experimental study of the 91Zr(n, γ) reaction up to 26 keV
(The American Physical Society, 2008)
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 91Zr with respect to the neutron magic nucleus 90Zr ...

Implications of Sm-151(n,gamma) cross section at n_TOF
(American Institute of Physics, 2006)
The accurate knowledge of the 151Sm(n,γ) cross section has important implications for the nuclear technologies as well as for fundamental studies. Due to its radioactivity, the only experimental data available on 151Sm ...
