Abstract

The radioactive decay of (187)Re -> (187)Os (t(1/2) = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the (187)Os abundance is the difference between the natural abundance and the corresponding s-process component. This component can be obtained via the well-established sigma N systematics using the neighboring s-only isotope (186)Os, provided the neutron-capture cross sections of both isotopes are known with sufficient accuracy. We report on a new set of experiments performed with a C(6)D(6) detector array at the n_TOF neutron spallation facility of CERN. The capture cross sections of (186)Os, (187)Os, and (188)Os have been measured in the neutron-energy range between 1 eV and 1 MeV, and Maxwellian-averaged cross sections were deduced for the relevant thermal energies from kT = 5 keV to 100 keV.

The radiogenic contribution to the (187)Os abundance is the difference between the natural abundance and the corresponding s-process component. This component can be obtained via the well-established sigma N systematics using the neighboring s-only isotope (186)Os, provided the neutron-capture cross sections of both isotopes are known with sufficient accuracy. We report on a new set of experiments performed with a C(6)D(6) detector array at the n_TOF neutron spallation facility of CERN. The capture cross sections of (186)Os, (187)Os, and (188)Os have been measured in the neutron-energy range between 1 eV and 1 MeV, and Maxwellian-averaged cross sections were deduced for the relevant thermal energies from kT = 5 keV to 100 keV.
