摘要：
The mass, charge, isotopic, and kinetic-energy distributions of fission fragments are studied within an improved scission-point statistical model in the reactions U-235 + n and (239) Pu + n at different energies of the incident neutron. The charge and mass distributions of the electromagnetic-and neutron-induced fission of Ra-214,Ra-218, U-230,U-232,U-238 are also shown. The available experimental data are well reproduced and the energy-dependencies of the observable characteristics of fission are predicted for future experiments.
