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 ...
