Nuclei in the Businaro–Gallone region are proposed as a relevant tool to study the dynamics of nuclear fission at high temperature. The influence of the macroscopic contribution to the driving potential energy landscape, and its strong dependence on angular momentum, is addressed in this contribution as a first step. An advanced model based on a four-dimensional Langevin approach is used to calculate fission-fragment mass and charge distributions. A good agreement with experiment is observed. The work is in progress, with the goal to explore the major assets of nuclei in this region for probing the modeling of inertia, friction and fluctuations, and particle evaporation.
