dc.description.abstractEnMean values of the number of protons and neutrons of the primary fission fragments at scission are determinedfor the asymmetric fission of 16 fissioning isotopes, from 219Ac up to 238Np. Our results confirm that the mainasymmetric fission mode around the heavier uranium isotopes is indeed characterized by an average atomicnumber around  ZH  = 54 in the heavy fission fragments. However, they also unambiguously show a stabilizationeffect in the light fission fragments around  NL  = 52–54 in the neutron-deficient thorium and actinium isotopes.This is a clear signature that these deformed proton and neutron shell closures around 54 play a major role inthe nuclear fission process. The evolution along the thorium chain shows that the neutron shell appears to bedominant in the asymmetric fission of the lighter thorium isotopes, in contrast to the heavier thorium isotopesfor which the stabilization originates from the proton shell.
