Re-evaluation of the ${}^{16}$O($n$,$\gamma$)${}^{17}$O cross section at astrophysical energies and its role as neutron poison in the $s$ process

Peter Mohr, Christian Heinz, Marco Pignatari +3

The doubly-magic nucleus ${}^{16}$O has a small neutron capture cross section of just a few tens of microbarn in the astrophysical energy region. Despite of this, ${}^{16}$O plays an i…
