英文摘要	We report the first (in)elastic scattering measurement of Al-25 + p with the capability to select and measure in a broad energy range the proton resonances in Si-26 contributing to the Mg-22(alpha, p) reaction at type I x-ray burst energies. We measured spin-parities of four resonances above the a threshold of Si-26 that are found to strongly impact the Mg-22(alpha, p) rate. The new rate advances a state-of-the-art model to remarkably reproduce light curves of the GS 1826- 24 clocked burster with mean deviation < 9% and permits us to discover a strong correlation between the He abundance in the accreting envelope of the photospheric radius expansion burster and the dominance of Mg-22(alpha, p) branch.
