Using a beam of the radioactive isotope 25Al, produced with the new resolut facility, we measured the direct (d,n) proton-transfer reaction leading to low-lying proton-resonances in 26Si. Here, we observed the lowest l = 0 proton resonance, identified with the 3+ state at 5.914 MeV excitation energy. This result eliminates the largest uncertainty about the astrophysical reaction rates involved in the nucleosynthesis of 26Al.
