Description

The dynamics of a split nucleus is simulated within a semiclassical description based on the Landau-Vlasov equation with a Uehling-Uhlenbeck collision term. Initially, the spherical system is suddenly divided into two equal parts boosted in opposite directions perpendicularly to the separation plane. The role of nucleon-nucleon collisions is studied in the damping of the collective energy and of deformations. The dynamic barrier profiles and heights are also strongly dependent on these two-body effects and may be compared with those of the liquid-drop model applied to excited systems
