Abstract

A measurement of the C-12 + O-16 breakup of Si-28 following Mg-24 scattering from targets of carbon, lithium oxide. and beryllium has been performed. A study of the relative energy of the correlated C-12 and O-16 fragments has allowed the excitation energy of states in Si-28 to be determined. A comparison of the excitation energy spectra in Si-28 Obtained from the three targets indicates that the same states are populated in the C-12(Mg-24,(CO)-C-12-O-16)Be-8, Li-7(Mg-24,(CO)-C-12-O-16)t, and Be-9(Mg-24,(CO)-C-12-O-16)(5) He reactions. The data support the hypothesis that the reaction mechanism populating the C-12 + O-16 breakup states observed in these channels is alpha transfer, and rule our an alternative involving resonant, or "doorway," states in the C-12 + Mg-24 compound system.
