\begin{document}$ ^{71} $\end{document}Ga(\begin{document}$n, \gamma $\end{document})\begin{document}$ ^{72} $\end{document}Ga reaction are measured, which are \begin{document}$9.14 \pm 0.81$\end{document} mb and \begin{document}$5.74 \pm 0.50$\end{document} mb at 2.15 and 3.19 MeV, respectively. The detailed uncertainty propagation and covariance analysis are also given. The \begin{document}$ ^{7} $\end{document}Li(\begin{document}$p,n$\end{document})\begin{document}$ ^{7} $\end{document}Be reaction was used to generate the neutrons, and the neutron flux was normalized using the \begin{document}$ ^{115} $\end{document}In(\begin{document}$n,n'$\end{document})\begin{document}$ ^{115} $\end{document}In\begin{document}$ ^{m} $\end{document}monitor reaction. The measured cross section data are compared with the data available in the EXFOR database, the data obtained using nuclear reaction model codes EMPIRE-3.2 and TALYS-1.95, and also the evaluated nuclear data from ENDF/B-VIII.0 and JEFF-3.1/A. The comparison shows that our result at 3.19 MeV is in good agreement with those of EMPIRE-3.2 and JEFF-3.1/A. Since there are no other measurements available at 3.19 MeV, our data could not be compared with literature data at 3.19 MeV, but they are consistent with the cross section values available at \begin{document}$2.98 \pm 0.26$\end{document} and \begin{document}$3.0 \pm 0.1 $\end{document} MeV. Our result at 2.15 MeV is slightly higher than the literature value available in EXFOR, evaluated value, and theoretically predicted result."> Measurement of neutron capture cross section on <sup>71</sup>Ga at 2.15 and 3.19 MeV and uncertainty propagation and covariance analysis -
