Computed final kinetic energies of fission fragments.

Analyzed dynamical effects during descent to scission.

Achieved agreement with experimental data for 258Fm fission.

Abstract

Recent progresses in the description of the latter stage of nuclear fission are reported. Dynamical effects during the descent of the potential towards scission and in the formation of the fission fragments are studied with the time-dependent Hartree-Fock approach with dynamical pairing correlations at the BCS level. In particular, this approach is used to compute the final kinetic energy of the fission fragments. Comparison with experimental data on the fission of 258Fm are made.
