/sup 12/C + /sup 12/C elastic scattering angular distributions have been measured between E/sub c.m./ = 6.50 and 7.05 MeV at intervals of 0.05 MeV. Resonances were observed in these yields at E/sub c.m./ = 6.64 and 6.83 MeV. A phase shift analysis of these data was carried out which resulted in assignments of J/sup (/ = 2/sup +/ (E/sub c.m./ = 6.64 MeV) and J/sup (/ = 4/sup +/ (E/sub c.m./ = 6.83 MeV) for the resonances. Carbon partial widths were determined by parametrizing the deduced phase shifts in terms of isolated Breit-Wigner resonances. The results, GAMMA/sub c/ = 29/sup +6//sub -/9 keV at E/sub c.m./ = 6.64 MeV and GAMMA/sub c/ = 11 +- 3 keV at E/sub c.m./ = 6.83 MeV, demonstrate unambiguously the quasi-molecular nature of the resonances.
