Small angle cross sections for the reactions /sup 16/O(/sup 16/O,..cap alpha..) /sup 28/Si and /sup 16/O(/sup 16/O,/sup 8/Be)/sup 24/Mg leading to ground states and first excited states of residual nuclei are reported for E/sub c.m./--12 to 20 MeV. Angular distributions are measured for all four exit channels at about forty energies in the neighborhood of resonancelike features. Resonant l values are inferred from both ..cap alpha../sub 0/ and /sup 8/Be/sub 0/ angular distribution and results are compared with other work. The distribution of maxima test shows that cross section maxima in the excitation functions are distributed randomly and that there is a low probability for any resonances in the energy range covered. Statistical model calculations with proper energy level densities and angular momentum conservation reproduce all the general features attributed to heavy-ion resonances.
