A systematic TDDFT data for nuclear fission analysis -Tin isotopes

Dissipation of nuclear many-body systems is studied by means of TDDFT+ Langevin model. Much attention is paid to the energy dependence of the friction coefficient, identifying the thermodynamic property of nuclear medium for given nucleon numbers, neutron-richness, and energies. In this article, following the preceding work showing a systematics on Z = 92 to 100 nuclei, macroscopic friction coefficients for Z = 50 nuclei are derived from a microscopic framework. The comparison between Z = 92 and Z = 50 cases clarifies the similarity and the difference of fissions between heavy and medium mass nuclei. It is not only the completion of a systematic theoretical database, but also pinning down the dissipative features of the r-process nuclei. In addition , the knowledge about the obtained fission probability and fission fragment yields is expected to be useful for both nuclear synthesis and nuclear engineering .
