Intermediate-Energy-Particle Induced Nuclear Fission: A dynamical statistical approach

A dynamical� statistical approach� which� takes� into� account� all the stages of fission induced by intermediate-energy particles (intranuclear cascade,�� evaporation�� cascade,�� fission� of� compound� nucleus,� and evaporation� from�� fission� fragments)� is� formulated.� In particular, the dynamics of the descent� of the fissioning nucleus from saddle point to scission point is described by the diffusion model. The data on fission of nuclei by intermediate-energy protons and stopped antiprotons have been analyzed� in� the� framework� of this approach and good agreement between theory and experiment observed.
