Ternary fission within statistical approach — •Alexander Andreev1,2, Gurgen Adamian2, Nikolai Antonenko1,2, Svetlana Ivanova2, Sergey Kuklin2, and Werner Scheid1 — 1Institut für Theoretische Physik der Justus-Liebig-Universität, Giessen, Germany — 2Joint Institute for Nuclear Research, Dubna, Russia
The formation of the ternary system is considered as the second step after the formation of the binary system by extracting one or several alpha-particles and neutrons from one or both binary fragments in the region of their interaction. Using this model, the charge number distributions for fission of the heavy nucleus 252Cf and the light nucleus 56Ni accompanied by various light charged particles (LCP) are described. The relative yields of different LCPs are calculated for fission of 252Cf. Based on the calculations of the excitation energy at scission, the neutron multiplicity distributions from the primary fission fragments of 252Cf are obtained. The mean total kinetic energy of fission fragments is also described. The results are compared with the experimental data.
