Abstract
The neutron capture cross section of $^{62}\mathrm{Ni}$ has been measured in the energy range relevant to the astrophysical $s$-process and Maxwellian-averaged cross sections (MACS) were extracted. The experiment was performed with an enriched $^{62}\mathrm{Ni}$ sample at a white neutron source using a 160 segment ${\mathrm{BaF}}_{2}$ detector array. The experimental results: $31.5\ifmmode\pm\else\textpm\fi{}2.{5}_{\mathrm{stat}}\ifmmode\pm\else\textpm\fi{}2.{2}_{\mathrm{sys}}$ mb (MACS at $\mathrm{kT}=25$ keV) and $25.8\ifmmode\pm\else\textpm\fi{}1.{8}_{\mathrm{stat}}\ifmmode\pm\else\textpm\fi{}1.{9}_{\mathrm{sys}}$ mb (MACS at $\mathrm{kT}=30$ keV) resolve a previous discrepancy between recent experiments.
