Neutron physics of the Re/Os clock. I. Measurement of the (n, γ) cross sections of 186, 187, 188 Os at the CERN n_TOF facility
(The American Physical Society, 2010)
The precise determination of the neutron capture cross sections of 186Os and 187Os is important to define the s-process abundance of 187Os at the formation of the solar system. This quantity can be used to evaluate the ...

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 ...
