  Prompt and $\beta$-delayed fission observables, such as the average number of
prompt and delayed neutrons, the independent and cumulative fission product
yields, and the prompt $\gamma$-ray energy spectra for the photonuclear
reactions on $^{235,238}$U and $^{239}$Pu are calculated with the
Hauser-Feshbach Fission Fragment Decay (HF$^3$D) model and compared with
available experimental data. In the analysis of neutron-induced fission
reactions to the case of photo-induced fission, an excellent reproduction of
the delayed neutron yields supports a traditional assumption that the
photo-fission might be similar to the neutron-induced fission at the same
excitation energies regardless of the spin and parity of the fissioning
systems.
