\begin{document}$ \pm $\end{document}3.97) muon-induced neutrons from an 820.28-day dataset at the first phase of CJPL (CJPL-I). Based on the muon-induced neutrons, we measured the corresponding muon-induced neutron yield in a liquid scintillator to be \begin{document}$(3.44 \pm 1.86_{\rm stat.}\pm $\end{document}\begin{document}$ 0.76_{\rm syst.})\times 10^{-4}$\end{document} μ−1g−1cm2 at an average muon energy of 340 GeV. We provided the first study for such neutron background at CJPL. A global fit including this measurement shows a power-law coefficient of (0.75\begin{document}$ \pm $\end{document}0.02) for the dependence of the neutron yield at the liquid scintillator on muon energy."> Measurement of muon-induced neutron yield at the China Jinping Underground Laboratory -
