We have started a research program at LNL with the apparatus 8πLP aimed at studying the fission dynamics in systems of intermediate fissility using light charged particles as probes. These systems are characterized by an evaporation residues (ER) cross section comparable or larger than the fission cross section, and by a relatively higher probability for charged particle emission in the pre-scission channel. In a theoretical framework in which time scale estimates rely on statistical model calculations, the additional analysis of particle emission in the ER channel allows to put more constraints on the input parameters of statistical and dynamical models. The presentation will report about an overall view of the systems studied so far and will provide clues for interesting physical cases. Recent advancement will also be discussed on the interplay between the fission and the evaporation residues channels as implied by a dynamical approach to the description of the fission process.

Abstract

We have started a research program at LNL with the apparatus 8πLP aimed at studying the fission dynamics in systems of intermediate fissility using light charged particles as probes. These systems are characterized by an evaporation residues (ER) cross section comparable or larger than the fission cross section, and by a relatively higher probability for charged particle emission in the pre-scission channel. In a theoretical framework in which time scale estimates rely on statistical model calculations, the additional analysis of particle emission in the ER channel allows to put more constraints on the input parameters of statistical and dynamical models. The presentation will report about an overall view of the systems studied so far and will provide clues for interesting physical cases. Recent advancement will also be discussed on the interplay between the fission and the evaporation residues channels as implied by a dynamical approach to the description of the fission process.
