Résumé

The $^{232}\mathrm{Th}$ photofission yields were measured by using bremsstrahlung at end-point energy of $50$ and $3500 MeV$. The nuclear charge and mass distributions of the fission fragments were obtained. The multi-modal fission approach was used for calculation of the symmetric and asymmetric channels in the photofission. The behaviour of asymmetric-symmetric components and $^{232}\mathrm{Th}$ fissility by different channels were obtained at the intermediate energies.
