  The time dependent equations of motion for the pair breaking effect were
corroborated with a condition that fixes dynamically the number of particles on
the two fission fragment. The single particle level scheme was calculated with
the Woods-Saxon superasymmetric two center shell model. This model provides a
continuous variation of the energies from one nucleus up to two separated
fragments. The dissipated energy resorts from the time dependent pairing
equations. A peculiar phenomenon was observed experimentally in cold fission:
the odd partition yields are favored over the even ones. This odd-even effect
for cold fission was explained microscopically.
