The /sup 12/C+ /sup 12/C elastic scattering has been measured for E/sub c.m./ = 14.6--31.3 MeV, theta/sub c.m./ = 30/sup 0/--110/sup 0/. The elastic data have been analyzed via a phase shift analysis, enabling the extraction of model independent sets of phase shift parameters. The extracted J/sup ..pi../ values for the intermediate structure resonances at E/sub c.m./ = 18.4, 19.3, and 20.3 MeV are 12/sup +/, 12/sup +/, and 12/sup +/ or 14/sup +/, respectively. The questions of ambiguities in the phase shift analysis and the comparison with J/sup ..pi../ values deduced from other experiments are discussed. Evidence is presented for the existence of gross structure resonances. The elastic scattering has also been analyzed using the sum-of-differences method to directly extract the total reaction cross section. The results of these analyses are compared to existing models of the origin of intermediate structure resonances.
