Abstract

The deformation properties of heavy nuclei undergoing the individual fission paths are studied. To understand the nuclear mass division process at low energy, fission events for the symmetric and asymmetric fission paths are analyzed from the overall fission events. The fragment mass-yield distributions for the symmetric and asymmetric fission paths in the fission processes of 210Po, 227Ac, 233Pa, 249Bk, and 259Md are systematically studied. Fission characteristics including the deformation of the fissioning nucleus at the scission configuration, the fragment massyield distributions, and the total kinetic energy release for individual fission paths are presented.
