dc.descriptionWe have made high-resolution neutron capture and transmission measurements on iso-topically enriched samples of 134Ba and 136Ba at the Oak Ridge Electron Linear Accel-erator (ORELA) in the energy range from 20 eV to 500 keV. Previous measurements had a lower energy limit of 3 - 5 keV, which is too high to determine accurately the Maxwellian-averaged capture cross section at the low temperatures (kT ¼ 6 - 12 keV) fa-vored by the most recent stellar models of the s-process. Our results for the astrophysical reaction rates are in good agreement with the most recent previous measurement at the classical s-process temperature, kT = 30 keV, but show significant differences at lower temperatures. We discuss the astrophysical implications of these differences.en_US
