  The nuclear fission of very neuron-rich nuclei related to the r-process is
essential for the termination of nucleosynthesis flows on the nuclear chart and
the final abundances. Nevertheless, most of the available fission data for the
r-process calculations are based on theory predictions, including
phenomenological treatments. In this study, we calculated a series of nuclear
fission distribution for neutron-rich nuclei away from the beta-stability line.
As most of these nuclei are experimentally unknown, we are based on theoretical
calculations based on the dynamical fission model with the Langevin method. We
performed fission distribution calculations for neutron-rich actinoid nuclei,
applicable to the r-process nucleosynthesis simulations. In the present paper,
we compared the obtained mass and charge distributions with experimental data.
We also show the results of the systematic behaviour of mass distribution for
neutron-rich U and Fm isotopes.
