Abstract

摘要

Binary fission observables are described within the scission-point model by calculating the potential energy with the dinuclear system model. For the description of ternary fission we extend the scission-point model of binary fission. The ternary system with a light nucleus between two heavy fragments is assumed to be formed from the binary configuration near the scission point. Charge number distributions, mean total kinetic energies and neutron multiplicity distributions are treated and compared with the experimental data for binary fission of actinides and for ternary fission of 252Cf accompanied by different light charged particles. The asymmetric mass distribution of fission fragments of 180Hg observed in the recent experiment is explained.
