Abstract

Al26 remains an intriguing target for observational γ-ray astronomy, thanks to its characteristic decay. The Al25(p,γ)Si26 reaction is the crucial link in a sequence that bypasses the production of the observable Alg26 in favor of the short-lived isomeric state; determining its astrophysical reaction rate across a range of stellar environments has been the focus of many studies. A reanalysis of previous work, utilizing recent improvements in excitation energies and ground state masses, is presented to reduce the ambiguities in the literature and provide focus to future measurements.
