The calculation of total fragment excitation energy for photofission of Uranium isotopes

Authors: MOJTABA JAMIATI, PAYAM MEHDIPOUR KALDIANI

Abstract: The total excitation energy as a function of fragment mass (TXE/A) are calculated for neutron induced fission of $^{235}$U and photofission of $^{238}$U by using the statistical model. With comparing the calculated results and the experimental data, the statistical model is modified. In new modified model, TXE are calculated by adding the neutron binding energy to the deformation energy. The calculated results using modified statistical model are in good agreement with the experimental data. Then, the total excitation energy as a function of fragment mass (TXE/A) are evaluated for photofission of Uranium isotopes.
