Fine structures by deformation in the mass energy distribution of fission fragments

It is shown within a seission point model that for a fixed mass and charge fragmentation the potential energy of the scission configuration has several minima as a function of the deformation parameters of the fragments. The scission at these minima leads to a relatively enhanced yield of the fragments with a certain TKE and creates fine structures in the TKE-mass distribution which are different from those produced by the odd-even effect.
