摘要：

A microscopic finite-temperature model based on time-dependent nuclear density functional theory (TDDFT) is employed to study the induced-fission process of 226Th. The saddle-to-scission dynamics of this process is explored, starting from various points on the deformation surface of Helmholtz free energy at a temperature that corresponds to the experimental excitation energy, and following self-consistent isentropic fission trajectories as they evolve toward scission. Dissipation effects and the formation of excited fragments are investigated and, in particular, the difference in the evolution of the local temperature along asymmetric and symmetric fission trajectories is studied. The relative entropies and entanglement between fission fragments emerging at scission are analyzed.
