  The evaluated nuclide yields, fragment mass and charge distributions, and
averaged total kinetic energy of fission fragments for the neutron-induced
fission of 30 actinide nuclei are well described in the new model, which
considers the fissioning scission system consisting of two heavy fragments and
an alpha-particle between them. The alpha-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 alpha-particle is fused with the
nearest heavy fragment after passing the saddle point, therefore, two final
fragments appear during fission. The quadrupole deformations of heavy fragments
are taken into account in the model. The fragment yields depend on the heights
of corresponding saddle points and the values of the equilibrium quadrupole
deformation of fragments.
