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 ...

Heat flux in a vibrated granular gas: the diffusive heat conductivity coefficient
(AIP Publishing, 2005)
The transport coefficient coupling heat flux and density gradient in a granular gas is measured by taking advantage of the existence of a minimum in the temperature profile of an open vibrated granular medium. This temperature ...

Measurement of capture cross sections of 90,91,92,94,96Zr isotopes at n_TOF
(AIP Publishing, 2005)
The neutron capture cross sections for Zr isotopes have important implications in nuclear technologies as well in the field of nuclear astrophysics. The innovative features of the n_TOF CERN facility allowed for an accurate ...

Green-Kubo representation of the viscosity of granular gases
(AIP Publishing, 2005)
The Green-Kubo representation of the shear viscosity of a dilute gas of inelastic hard disks derived from the Boltzmann equation is evaluated by means of the direct simulation Monte Carlo method. The relationship between ...

Measurements at n_TOF of the neutron capture cross section of minor actinides relevant to the nuclear waste transmutation
(American Institute of Physics, 2005)
Accurate and reliable neutron-capture cross-section data for actinides are necessary for the proper design, safety regulation, and precise performance assessment of transmutation devices such as Fast Critical Reactors or ...

The n(-)TOF facility at CERN: Performances and first physics results
(AIP Publishing, 2005)
The neutron Time of Flight (n_TOF) facility at CERN is a source of a wide-range (1 eV<En<250 MeV) flux of neutrons, generated by spallation of 20-GeV/c protons onto a solid lead target. The goal of the n_TOF is to provide ...

New Measurement of the Capture Cross Section of Bismuth and Lead Isotopes
(American Institute of Physics, 2005)
All the stable lead isotopes and 209Bi have been recently measured at n_TOF [1] (CERN) in the range from 1 eV up to 1 MeV, using an optimized experimental setup. A set of two homemade C6D6 detectors with carbon-fibre canning ...

High-resolution study of Np-237 fission cross section from 5 eV to 1 MeV
(AIP Publishing, 2005)
A series of measurements of 237Np fission cross section have been performed at the CERN spallation neutron facility n_TOF which covers a wide energy range from 1 eV up to 250 MeV. A fast ionization chamber (FIC) was used ...

Is the optical model valid for the scattering of exotic nuclei?
(American Institute of Physics, 2005)
The optical model, and its applications to elastic, inelastic and transfer reactions is reviewed. The applicability of the optical model to the collisions of exotic nuclei is discussed. The sensitivity of recent experimental ...
