\begin{document}${\sigma _{\rm th}} = 8.35$\end{document}mb is in good agreement with experimental data. We considered five resonances at the excitation energies Ex from 7.371 MeV up to 10.570 MeV corresponding to the following states with \begin{document}${J^\pi }$\end{document}(Ex, MeV): \begin{document}${3^ - }$\end{document}(7.371), \begin{document}${2^ + }$\end{document}(7.542), \begin{document}${3^ + }$\end{document}(9.4), \begin{document}${2^ + }$\end{document}(9.56), and \begin{document}${3^ - }$\end{document}(10.570). The partial and total 9Be(n,γ0+1+2+3+4+5)10Be reaction rates are calculated at temperatures from 0.001 to 10 T9. Contrary to the available data, we propose that the rise in the reaction rate near factor five at T9 >1 is mainly due to the first \begin{document}${3^ - }$\end{document}(ER = 0.559 MeV) resonance. We foresee this contrast as arising from different model approaches."> Radiative <sup>9</sup>Be(n,γ<sub>0+1+2+3+4+5</sub>)<sup>10</sup>Be reaction rate in the potential cluster model -
