\begin{document}$ p,\gamma$\end{document})26Al reactions determine the production of 26Al, which is one of the most important long-lived radioactive nuclei in nuclear astrophysics. In this article, we report our first experiment using the intense proton beam of approximately 2 mA provided by the JUNA accelerator ground laboratory and a new technique that can minimize the composition change of targets under intense beam irradiation. The resonance strengths and branching ratios of E = 214, 304, and 326 keV resonances in the reactions of 24Mg(\begin{document}$ p,\gamma$\end{document})25Al, 25Mg(\begin{document}$ p,\gamma$\end{document})26Al, and 26Mg(\begin{document}$ p,\gamma$\end{document})27Al, respectively, were measured with high accuracy. The success of this experiment provides a good calibration for the nuclear astrophysical experiment at the Jinping underground laboratory."> Direct measurement of the resonance strengths and branching ratios of low-energy (<i>p</i>, <i>γ</i>) reactions on Mg isotopes -
