Backward-angle excitation functions (theta/sub c.m./ = 180/sup 0/ +- 5/sup 0/) have been measured for the systems /sup 16/O + /sup 28/Si and /sup 12/C + /sup 28/Si for elastic and inelastic scattering to the first excited state in /sup 28/Si. Over the investigated energy range, 17 9 or approx. = E/sub c.m./ 9 or approx. = 37 MeV, the elastic and inelastic data exhibit gross structure resonances of widths between 1 and 2 MeV modulated by a finer structure for /sup 12/C + /sup 28/Si (..delta..E/sub c.m./ 9 or approx. = 250 keV). Shape resonances with different principal quantum numbers are suggested as an explanation of resonances.
