Monte Carlo calculations of fission of actinides and pre-actinides induced by protons and neutrons in the energy range from 100 MeV to 1 GeV are carried out by means of a recent version of the Li\`ege Intranuclear Cascade Model, INCL++, coupled with two different evaporation-fission codes, GEMINI++ and ABLA07. In order to reproduce experimental fission cross sections, model parameters are usually adjusted on available (p,f) cross sections and used to predict (n,f) cross sections for the same isotopes.Comment: 36 pages, 18 figures, to appear in Nuclear Physics

A recently built, new-generation experimental set-up, made it possible the first complete isotopic identification and momentum determination of the two fragments produced in fission reactions investigated in inverse kinematics. These experiments provide new insights into the static and dynamic properties of the fission process. In particular we have investigated ground-to-saddle transient effects and saddle-to-scission times using proton-induced fission reactions on 208 Pb. The shorter fission times, due to the high excitation energies gained by the fissioning nuclei, provide better sensitivity of the fission clocks used to investigate the fission dynamics.

Abstract. The first ever achieved full identification of both fission fragments, in atomic and mass number, made it possible to define new observables sensitive to the fission dynamics along the fission path up to the scission point. Moreover, proton-induced fission of 208 Pb at high energies offers optimal conditions for the investigation of dissipative, and transient effects, because of the high-excitation energy of the fissioning nuclei, its low angular momentum, and limited shape distortion by the reaction. In this work we show that the charge distribution of the final fission fragments can constrain the ground-to-saddle dynamics while the mass distribution is sensitive to the dynamics until the scission point.
