Seven elastic scattering angular distributions have been measured for the system /sup 16/O+/sup 28/Si around the first resonant structure observed in the theta/sub c.m./ = 180/sup 0/ excitation function at 21.1 MeV center of mass energy just above the Coulomb barrier. Optical model, Regge pole, and phase shift analyses have been performed. These complementary analyses show that several partial waves contribute to the backward rise and the oscillatory behavior of the elastic scattering angular distributions. The 21.1 MeV resonant structure can be interpreted in terms of several overlapping resonances. Tentative spin assignments are made for these states.
