Abstract：
In the frame of the multichannel fission model with the random neck rupture,the fragment yield and total kinetic energy distributions of the neutron induced ²³⁵U(n,f) fission covering the incident neutron energy range from 0 to 6MeV are calculated.The change of channel probabilities with the neutron incident energy is obtained by fitting experimental data.The theoretical results are in accord with the experimental data.
