Abstract

Measurements have been made of the radiative widths of the lowest energy resonances in ${}^{13}C$ and ${}^{16}O$ . Maxwellian-averaged capture cross sections calculated for $k T = 30$ keV indicate that ${}^{13}C$ and ${}^{16}O$ could not have been significant neutron poisons in $s$ -process nucleosynthesis.
