Excitation functions of the /sup 24/Mg(/sup 16/O,/sup 12/C)/sup 28/Si and /sup 24/Mg(/sup 16/O,/sup 16/O)/sup 24/Mg reactions to the ground states and first-excited 2/sup +/ states in /sup 28/Si and /sup 24/Mg have been measured at theta/sub c.m./=180/sup 0/ over the energy range 24< or =E/sub c.m./< or =40 MeV, where the /sup 24/Mg(/sup 16/O,/sup 12/C)/sup 28/Si reaction is known to exhibit a strong resonant behavior at forward angles. The four measured excitation functions show prominent structures, about 1 MeV wide, strongly correlated in the elastic and inelastic channels. Angular distributions in the range 110/sup 0/< or =theta/sub c.m./< or =180/sup 0/ were measured at E/sub c.m./=27.8, 30.8, and 36.2 MeV. At 27.8 and 36.2 MeV, where prominent peaks exist in the (/sup 16/O,/sup 12/C) backward-angle excitation function, the angular distributions of the transfer to the 0/sup +/ ground state are strongly rising toward 180/sup 0/ and have an oscillatory shape. The partial waves L20,22and 26, respectively, are predominant at these two energies. At 30.8 MeV the data indicate the interference between odd and even partial waves.
