Abstract：
For the n+ ²³⁵U fission reaction, the total excitation energy partition of the fission fragments, the average neutron kinetic energy < ε>( A) and the total average energies E _γ( A) removed by γ rays as a function of fission fragment mass are given at incident energies up to 20 MeV. The prompt neutron multiplicity as a function of the fragment mass, ν(A), for neutron-induced fission of ²³⁵U at different incident neutron energies is calculated. The calculated results are checked with the total average prompt neutron multiplicities νand compared with the experimental and evaluated data. Some prompt neutron and γ emission mechanisms are discussed.
