Abstract Elastic and inelastic scatterings cross-sections of12C+12C in the energy range 11–24 MeV/n have been analyzed within the coupled channels framework including appropriate symmetrization. The set obtained withr 0=1.01 fm,r I =0.86 fm for seven incident energies gave the best agreement with the data and could be, therefore, considered as really significant when compared with other sets. Coupled channels calculations have been made to fit the data and it has been found that they require a reduction of the imaginary potential. The total reaction cross-sectionσ R (E) determined from this analysis is in good agreement with a direct and recent measurement of σ R . Quadrupole deformation parameterβ 2 has been extracted and compared with those obtained for proton and alpha scatterings. Some small energy dependence of β2 over this energy range has been found, ¦β 2¦ ∼0.39–0.47. Finally, these calculations further confirm that β2 depends on the probe used in the various scattering experiments. For composite projectile such asα or12C,β 2 is clearly smaller than that one for nucleon as projectile.
