Study of low-energy fission actinide-nuclei with Fourier shape parametrization

In present work the calculations of characteristics of the low-energy binary fission of actinide nuclei were presented. These values were obtained in the framework of Langevin equation formalism, where quantities related with nuclear surface were performed within Fourier shape parametrization. Using of global deformation parameters approach for obtaining of the excitation energies formed fission fragments at the neck breaking moment were performed. Making an assumption that cooling of primary fragments passes via neutron evaporation helped to build the secondary fragments mass yields. Comparative analysis of mass distributions for neutron induced and spontaneous fission nuclei with Z in region 92-98 showed good agreement with analogous experimental data. (author)
