Driving potential and fission-fragment charge distributions

Abstract We propose an efficient approach to describe the fission-fragment charge yields for actinides based on driving potential of fissioning system. Considering properties primary fission fragments at their ground states, potential, which represents energies system around scission configuration and closely relates fragments, can be unambiguously quickly obtained from Skyrme energy-density functional together with Weizsäcker–Skyrme mass model. The distributions thermal-neutron-induced spontaneous a series actinides, especially odd–even staggering in distributions, well reproduced. Nuclear dynamical deformations pairing corrections play important role distributions.
