This contribution reports on measurements of the neutron capture cross sections of 186Os, 187Os and 188Os from the eV region to 1 MeV at the CERN/n_TOF facility and of the inelastic scattering cross section of 187Os around 30 keV at the Karlsruhe 3.7 MV Van de Graaff accelerator. Based on these results and on a detailed resonance analysis, improved Maxwellian-averaged cross sections were obtained for thermal energies between 5 keV and 100 keV. The implications of these results for the Re/Os clock are discussed.

Abstract
This contribution reports on measurements of the neutron capture cross sections of 186Os, 187Os and 188Os from the eV region to 1 MeV at the CERN/n_TOF facility and of the inelastic scattering cross section of 187Os around 30 keV at the Karlsruhe 3.7 MV Van de Graaff accelerator. Based on these results and on a detailed resonance analysis, improved Maxwellian-averaged cross sections were obtained for thermal energies between 5 keV and 100 keV. The implications of these results for the Re/Os clock are discussed.File in questo prodotto:
