The Galactic 1.809-MeV-ray signature from thedecay ofis a dominant target of-ray astronomy, of which a significant component is understood to originate from massive stars. Thereaction is a major destruction pathway forat stellar temperatures, but the reaction rate is poorly constrained due to uncertainties in the strengths of low-lying resonances in. Thereaction has been employed in inverse kinematics to determine the spectroscopic factors, and hence resonance strengths, of proton resonances invia mirror symmetry. The strength of the 127-keV resonance is found to be a factor of 4 higher than the previously adopted upper limit, and the upper limit for the 68-keV resonance has been reduced by an order of magnitude, considerably constraining thedestruction rate at stellar temperatures.
