  An outstanding problem in the theory of nuclear fission is understanding the
Hamiltonian dynamics at the scission point. Here we apply the Generator
Coordinate Method to calculate decay widths for pre-scission configurations
into the two-fragment continuum. Transitions that are allowed under diabatic
dynamics can have widths up to several MeV. For non-diabatic decays through the
pairing interaction, typical widths to a specific final state channel are 2-3
orders of magnitude smaller. The nucleus U-236 is taken as a representative
example in the calculations.
