Charge distribution of photofission products of $^{232}\mathrm{Th}$ and $^{238}\mathrm{U}$

The $^{232}\mathrm{Th}$ and $^{238}\mathrm{U}$ photofission yields were measured by using bremsstrahlung at end-point energy of $50$ and $3500$ MeV. The nuclear charge distributions of the fission fragments were investigated and necessary parameters were determined: the most probable charge ($Z_p$) and the width parameter ($C$). The obtained data were compared with accounts on models $\mathrm{UCD}$ and $\mathrm{MPE}$. The universal picture of fission processes with different particles was confirmed.
