  The dynamics of low-energy induced fission is explored using a consistent
microscopic framework that combines the time-dependent generator coordinate
method (TDGCM) and time-dependent nuclear density functional theory (TDDFT).
While the former presents a fully quantum mechanical approach that describes
the entire fission process as an adiabatic evolution of collective degrees of
freedom, the latter models the dissipative dynamics of the final stage of
fission by propagating the nucleons independently toward scission and beyond.
By combining the two methods, based on the same nuclear energy density
functional and pairing interaction, we perform an illustrative calculation of
the charge distribution of yields and total kinetic energy for induced fission
of $^{240}$Pu. For the saddle-to-scission phase a set of initial points for the
TDDFT evolution is selected along an iso-energy curve beyond the outer fission
barrier on the deformation energy surface, and the TDGCM is used to calculate
the probability that the collective wave function reaches these points at
different times. Fission observables are computed with both methods and
compared with available data. The relative merits of including quantum
fluctuations (TDGCM) and the one-body dissipation mechanism (TDDFT) are
discussed.
