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.
