Abstract
The energy sorting at scission is treated fully microscopically in terms of the time dependent pairing equations. These equations for the intrinsic motion are mixed with a dynamical particle number projection condition on the primary fragments. The shape sequences during the disintegration resort from the minimal action principle. For this purpose, the potential energy is computed within the macroscopic-microscopic approach and the inertia within semi-adiabatic cranking approximation. The disentanglement of the wave function in two semi-spaces is realized within the Woods-Saxon two-center shell model. That allows a separation of the pairing field onto two sub-spaces. It is shown that the excitation energies of the fission fragments depend on a delicate interplay between their structure at and their deformations at scission.
