Going beyond statistical models for fission in the Businaro-Gallone region

Abstract : Dynamical calculations based on a four-dimensional stochastic Langevin approach are used to study fission in the Businaro-Gallone region. The use of such a model to map the Businaro-Gallone transition is proposed for the first time, exploiting recent theoretical developments and computing resources. The significance of the approach is supported by a systematic comparison with measurements for a set of systems. Experimental observations on fission-fragment charge distributions, which remained unexplained within a unified framework so far, are described by the dynamical model in a consistent manner. A detailed analysis reveals the interplay of dynamical effects, going beyond statistical-models interpretation and suggesting to revisit the commonly admitted idea about the prevalence of static effects in the Businaro-Gallone region.
