The fissioning scission system in the model consists of two heavy fragments and 
-particle between them. The -particle has its origin in the neck nucleons. The yield of fission fragments in the model is linked to the number of states over the barrier of the saddle point, which is between the contacting and well-separated fission fragments. The quadrupole deformations of heavy fragments are taken into account in the model. The correlation between the values of the equilibrium quadrupole deformation parameter of the fragments and the yield of these fragments is shown. The experimental yields of fragment mass and charge distributions for the neutron-induced fission of 30 actinide nuclei are well described in the model. The values of the average total kinetic energy for the neutron-induced fission of considered nuclei are well agreed with the available experimental data.
