Description
A new measurement of 25Al+p resonant scattering was performed up to the astrophysically interested energy region of 22Mg(a, p)25Al. Several resonances were observed in the excitation functions, and their level properties have been determined based on an R-matrix analysis. An improved reaction rate of 22Mg(a, p)25Al was determined based on the level properties of the corresponding resonances. 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%.
