  Photofission of actinides is studied in the region of nuclear excitation
energies that covers the entire giant dipole resonance (GDR) region. The mass
distributions of $^{238}$U photofission fragments have been explored
theoretically for eight different endpoint bremsstrahlung energies from 11.5
MeV to 67.7 MeV which correspond to average photon energy of 9.09 MeV to 15.90
MeV. Among these energies, the 29.1 MeV corresponds to the average photon
energy of 13.7$\pm$0.3 MeV which 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 producing
nuclei and their neutron-richness is investigated.
