Description
The strong quadrupolar component of the Coulomb field between newly formed fission fragments
can a?ect the internal energy of the fragments and their angular momentum. Previous estimates
of these effects gave contradictory conclusions about their magnitude. Here we calculate them by
solving the time-dependent Hamiltonian equation for the daughter 100Zr produced in the fission
reaction n + 235U ! 136Te + 100Zr. The Hamiltonian was constructed from the projected angular
momentum eigenstates of an aligned deformed mean-field configuration. For typical initial
conditions, the average angular momentum of the lighter fragment increases by 1.5 - 3 units.
