Description
The nuclear fission of very neuron-rich nuclei is essential for the termination of the r-process flow on the nuclear chart and the determination of the final abundances. Nevertheless, most of the available fission data for neutron-rich nuclei are based on theory predictions mostly by phenomenological treatments. In this study, we calculated a series of nuclear fission distribution for neutron-rich nuclei away from the stability line. We are based on theoretical calculations based on the dynamical fission model with the Langevin method. We compared the obtained mass and charge distributions with experimental data and the results of the GEF code. We also show the results of the systematic behaviour of mass distribution for neutron-rich U and Fm isotopes: the asymmetric feature of fission changes symmetric as isotopes become neutron rich.
