Abstract:
The long-lived radionuclide
26Al is one of the most important nuclide in the study of interstellar medium,
\gamma
-ray astronomy and the formation of the solar system. The three celestial sites most likely to synthesize
26Al are related to the
25Mg (
\rm p,\,\rm\gamma 
)
26Al reaction, therefor the accurate measurement of the near-threshold level resonant strength and astrophysical reaction rates is of great significance to understand the origin of
26Al in the universe. This article reviews the experimental research methods and the recent progress in the
25Mg (
\rm p,\,\rm\gamma )
26Al experiment. Especially, the indirect measurement and direct measurement plan for this reaction in China is introduced. The current indirect measurement results have improved the experimental accuracy of the
25Mg (
\rm p,\,\rm\gamma )
26Al astrophysics reaction rates, which can help us estimate the yield of direct measurement and optimize the experimental design. The direct measurement results of high-energy level resonance are in good agreement with the existing experiments within the error bars, indicating that the designed detection system by this project is in good working condition and can be competent for the experiment of Jinping deep underground nuclear astrophysics.
