Scission configurations and the spin of fission fragments
L. Bonneau, P. Quentin1, I.N. Mikhailov2

After a brief presentation of the orientation pumping mechanism as a mean to generate finite average angular momenta in oriented systems, some consequences are drawn for the spin of fission fragments. Through a crude model approximation for the scission configurations, the results of microscopic calculations of fragment deformabilities are then used to deduce from the above mechanism, a distribution of fission fragment spins as a function of the total fragment excitation energy. A fair qualitative agreement with available data is demonstrated.
