In the frame of the multichannel fission and random neck rupture model
, the fragment mass, average kinetic energy distributions, and the neu
tron multiplicities of the neutron-induced fissions of U-233,U-235,U-2
38 are calculated covering the incident neutron energy range from ther
mal to 6 MeV. The theoretical results are in accord with the experimen
tal data. The dependence of the fission channel probability on the exc
itation energy has been investigated.
