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 ...

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% ...
