  Photofission of actinides is studied in the region of nuclear excitation
energies that covers the entire giant dipole resonance (GDR) region. A
comparative analysis of the behavior of the symmetric and asymmetric modes of
photon induced fission as a function of the average excitation energy of the
fissioning nucleus is performed. The mass distributions of $^{238}$U
photofission fragments are obtained at the endpoint bremsstrahlung energy of
29.1 MeV which corresponds to mean photon energy of 13.7$\pm$0.3 MeV that
coincides with GDR peak for $^{238}$U photofission. The integrated yield of
$^{238}$U photofission as well as charge distribution of photofission products
are calculated and its role in the production of neutron-rich nuclei and their
exoticity is explored.
