dc.titleNeutron physics of the Re/Os clock. I. Measurement of the (n, gamma) cross sections of (186,187,188)Os at the CERN n_TOF facilityen
heal.abstractThe precise determination of the neutron capture cross sections of (186)Os and (187)Os is important to define the s-process abundance of (187)Os at the formation of the solar system. This quantity can be used to evaluate the radiogenic component of the abundance of (187)Os due to the decay of the unstable (187)Re (t(1/2) = 41.2 Gyr) and from this to infer the time duration of the nucleosynthesis in our galaxy (Re/Os cosmochronometer). The neutron capture cross sections of (186)Os, (187)Os, and (188)Os have been measured at the CERN n_TOF facility from 1 eV to 1 MeV, covering the entire energy range of astrophysical interest. The measurement has been performed by time-of-flight technique using isotopically enriched samples and two C(6)D(6) scintillation detectors for recording the prompt. rays emitted in the capture events. Maxwellian averaged capture cross sections have been determined for thermal energies between kT = 5 and 100 keV corresponding to all possible s-process scenarios. The estimated uncertainties for the values at 30 keV are 4.1, 3.3, and 4.7% for (186)Os, (187)Os, and (188)Os, respectively.en
