Abstract: Quasielastic (QE) excitation function measurements have been carried out for the C-12+Th-232 fissile system at theta(lab) = 170 degrees in the energy range of E-lab = 51-79 MeV. The data has been analyzed to obtain a representation of the fusion barrier distribution, which has been compared with that obtained from fusion-fission excitation function measurements available from literature. The QE data have also been analyzed in the framework of generalized elastic scattering model to obtain the mean-square average compound nuclear spin ([l(2)]) values, which has been compared with the prediction of standard fusion model (CCDEF) calculations and also with that obtained from fission fragment angular anisotropy measurements. The results show that the barrier distributions obtained from QE and fission excitation function measurement are consistent with each other. The [l(2)] values are also consistent with prediction of CCDEF calculations, but are in disagreement with the experimental [l(2)] values obtained from fission fragment anisotropy measurements.
