Fission dynamics in the proton induced fission of heavy nuclei

Abstract Multi-parameter correlation study of the reaction 242 Pu(p, f) at E p = 13, 20 and 55 MeV has been carried out. Fission fragment mass and kinetic energy distributions and the double differential neutron spectra have been measured. It was observed that the two-humped shape of mass distributions prevailed up to highest proton energy. Manifestation of the nuclear shell Z = 28 near fragment mass A fr = 70 has been detected. The experimental results were analyzed in the framework of a time-dependent statistical model with inclusion of nuclear friction effects in the fission process.
