Abstract
The γ-decay properties of an excited state in 26Al at 6398.3(8) keV have been reexamined using the 11B+16O fusion-evaporation reaction. This level represents a key 93.1(8)-keV resonance in the 25Mg+p system and its relative branching to the 26Al ground state, f0, has been determined to be 0.76±0.03 (stat.) ±0.10 (syst.). This is a significantly higher value than the most recent evaluation and implies a considerable increase in the production of cosmic γ rays from 26Al radioactivity.
