TRAJECTORY CALCULATIONS OF TERNARY FISSION OF NUCLEI

The analysis of ternary fission of Cf-252 and U-236 nuclei is performe d within the framework of a model of trajectory calculations. The obta ined results show that the configuration of a ternary nuclear system f ormed near the scission point is compact. The initial kinetic energies of fragments are approximately 5 - 7 MeV. The emission point of a lig ht particle is positioned on the fission axis within a region of appro ximately 2 fm. A description of polar emission of alpha-particles in t ernary fission is obtained within the framework of a unified mechanism involving equatorial emission. Compactness of the configuration of a ternary nuclear system, localization of the emission point on the fiss ion axis, and dissipative friction forces determine the probability of the nuclear orbiting in the formation of particles in the neck region and establish a certain balance between nuclear and Coulomb forces.
