Abstract
Excitation functions have been measured for the /sup 24/Mg(/sup 16/O,/sup 12/C)/sup 28/Si reaction populating states in /sup 28/Si with 6.4< or =E/sub x/< or =10 MeV over the energy range 24< or =E/sub c.m./< or =36 MeV. At each incident beam energy, cross sections were measured at three angles over the range 17/sup 0/< or =theta/sub c.m./< or =21/sup 0/. More complete angular distributions with 10/sup 0/< or =theta/sub c.m./< or =50/sup 0/ were measured at E/sub c.m./=30.5 and 32.6 MeV. Resonancelike structures are observed in the excitation functions and strongly correlate with those seen previously at forward angles for the /sup 24/Mg(/sup 16/O,/sup 12/C)/sup 28/Si(g.s.) transition. Estimates are made for the partial decay widths of the resonance at E/sub c.m./=30.8 MeV to the excited states in /sup 28/Si. Using different background assumptions, between 5 and 40% of the total width of this resonance can be atrributed to /sup 12/C+/sup 28/Si* (E/sub x/<10 MeV) decays.
