Abstract

A state-of-the-art three-dimensional Langevin approach is used to explore the inﬂuence of the potential-energy surface on the dynamical evolution of a system along its path to ﬁssion. Two macroscopic models have been used to parametrize the energy landscape: the Finite Range Liquid Drop Model (FRLDM) [1] and the Lublin-Strasbourg Drop (LSD) model [2]. The former is commonly used for the description of the ﬁssion of heavy nuclei. The latter, developed recently, is expected to be more realistic for describing the shapes experienced by fissioning medium-mass nuclei.
