- Description
- A two hundred experimental photofissility data obtained in the quasi-deuteron region (<math>\backsim 30-140</math> MeV) of photonuclear absorption covering the target nuclei <math>^{27} Al, ^{nat} Ti, ^{51} V, ^{154} Sm, ^{174}Yb, ^{nat}Hf, ^{181}Ta, ^{nat}W, ^{nat}Re, ^{nat}Os, ^{nat} Pt, ^{197}Au, ^{nat}Tl, ^{208}Pb, ^{nat}Pb \,\!</math> and <math>^{209}Bi\,\!</math> have been analysed in the framework of the current, two-step model for intermediate-energy photofission reactions. The incoming photon is assumed to be absorbed by a neutron-proton pair (Levinger's quasi-deuteron model), followed by a mechanism of evaporation-fission competition for the excited residual nuclei. The experimental features of photofissility have been reproduced successfully by the model.
