Abstract (english)
A model is developed to calculate the total kinetic energy (TKE) distribution of fission fragments in the framework of the time-dependent generator coordinate method, extended to include dissipation effects in the description of induced fission dynamics. Starting from an expression for the dissipative term in the generator co-ordinate method Hamiltonian that determines the time evolution of a statistical collective wave function, derived in the first part of this work, the integrated flux of the probability current through the scission hypersurface can be computed at different temperatures. The kinetic energy at scission for a specific pair of fragments at a given temperature is determined by the energy balance formula. By folding the kinetic energies of the fragments with the flux of the probability current, the TKE distribution is calculated. The method is illustrated with a calculation of the TKE distribution for induced fission of 228Th, in the three-dimensional space of collective coordinates: axially symmetric quadrupole and octupole deformations, and nuclear temperature.
