Ni63(n,γ) cross sections measured with DANCE

The neutron capture cross section of the $s$-process branch nucleus $^{63}\mathrm{Ni}$ affects the abundances of other nuclei in its region, especially $^{63}\mathrm{Cu}$ and $^{64}\mathrm{Zn}$. In order to determine the energy-dependent neutron capture cross section in the astrophysical energy region, an experiment at the Los Alamos National Laboratory has been performed using the calorimetric $4\ensuremath{\pi}\phantom{\rule{4pt}{0ex}}{\mathrm{BaF}}_{2}$ array DANCE. The ($n,\ensuremath{\gamma}$) cross section of $^{63}\mathrm{Ni}$ has been determined relative to the well-known $^{197}\mathrm{Au}$ standard with uncertainties below 15%. Various $^{63}\mathrm{Ni}$ resonances have been identified based on the $Q$ value. Furthermore, the $s$-process sensitivity of the new values was analyzed with the new network calculation tool NETZ.
