Fission dynamics from saddle-to-scission, and even beyond, is a non-equilibrium quantum process and its description within a fully quantum many-body framework has been a formidable problem to find its solution in theoretical physics for more than 8 decades now. Within the Time-Dependent Density Functional Theory (TDDFT) extended to superfluid fermion systems, which is a mathematically...

18. How does the angular momentum of fission fragments depend on their mass? An insight from microscopic theory

Recent experiments have provided strong evidence that the angular momentum of fission fragments follows a sawtooth pattern as a function of their mass. Reproducing this behavior without fitting it explicitly requires microscopic models capable of describing the physics of scission without adjustable parameters. Using the Hartree-Fock-Bogoliubov theory and symmetry restoration techniques, we...

The strong quadrupolar component of the Coulomb field between newly formed fission fragments
can a?ect the internal energy of the fragments and their angular momentum. Previous estimates
of these effects gave contradictory conclusions about their magnitude. Here we calculate them by
solving the time-dependent Hamiltonian equation for the daughter 100Zr produced in the fission
reaction n +...
