Description

Neutron elastic and inelastic scattering cross sections have been measured for 60.5 keV neutrons incident on /sup 187,188/Os. For 187Os the cross section for elastic scattering is 11 b and for inelastic scattering to the 9.75-keV level it is 1.13 b. These results and other scattering properties are represented in phase shift and scattering potential analyses, which then allow the prediction of neutron capture by 187Os nuclei in the 9.75-keV and ground levels. Capture rates thus provided are used in the Re-Os nucleochronology, and lead to a long galactic age, about 18 to 20 Gyr
