Observation ofC12+C12resonances as final states in theC12(O16,α)Mg24reaction

Abstract
Arguments based on recent level width and α branching ratio measurements are presented to show that C12 + C12 resonances may not be populated by the C12(O16,α)Mg24 reaction as reported. Recent α spectra obtained at high bombarding energy are explained assuming O16 projectile excitation followed by α emission.
