Abstract：
The distribution properties of the total fission kinehc energy and of the mass of fission fragments at different initial excitation energies of hot nuclei in the reaction 25MeV/u ⁴⁰Ar+²⁰⁹Bi are investigated. The initial excitation energies are obtained according to the linear momentum transfer. The experimental results show that the fission kinetic energy distribution is similar to the case of compound nuclei with lower excitation energy when the initial excitation energy of hot nuclei is below 380MeV. While the inihal excitation energy is above 380MeV, the most probable value of fission kinehc energy increases with the inihal excitahon energy. The fission energy spectra become asymmetric due to an enhancement of the yield at higher kinetic energies, and the width of mass distribution increases rapidly.
