The recent observation of neutron stars merger by the Laser Interferometer
Gravitational-Wave Observatory (LIGO) collaboration and the measurements of the
event’s electromagnetic spectrum as a function of time for different
wavelengths have altered profoundly our understanding of the mbox{$r$-process}
site as well as considerably energized nuclear astrophysics research efforts.
mbox{$R$-process} abundances are a key element in mbox{$r$-process}
simulations, as a successful calculation must account for these abundances in
the final debris of a stellar cataclysmic event. In this article, mankind’s
complete knowledge of neutron cross sections obtained over the last 80 years,
as encapsulated in the latest release of the Evaluated Nuclear Data File
(ENDF/B) library, is used to obtain solar system mbox{$r$-process} abundances
in a comprehensive data approach. ENDF/B cross sections have been successfully
used for decades in nuclear power and defense applications and are now used to
obtain mbox{$r$-process} abundances in a fully traceable and documented way.
This article mbox{$r$-process} abundances provide complementary insights on
the astrophysical events, overall quality of neutron capture data in the
astrophysical region of temperatures, and demonstrate issues with the
mbox{$s$-process} contribution subtraction procedure.
