Resum
Classical novae are expected to contribute to the 1809-keV Galactic ¿-ray emission by producing its precursor Al26, but the yield depends on the thermonuclear rate of the unmeasured Al25(p,¿)Si26 reaction. Using the ß decay of P26 to populate the key Jp=3+ resonance in this reaction, we report the first evidence for the observation of its exit channel via a 1741.6±0.6(stat)±0.3(syst) keV primary ¿ ray, where the uncertainties are statistical and systematic, respectively. By combining the m...
