New insights into fission from recent experiments: What drives fission across the nuclear chart?
Christelle SCHMITT (IPHC Strasbourg)

Nuclear fission owes its name by the fact that it resembles the division of living cells. But hidden behind is the complex re-arrangement of a many-body quantum system involving two types of nucleons, the protons and the neutrons. As a consequence, the process revealed to be a rich laboratory for studying fundamental nuclear properties, in general, and dynamical aspects of nuclear reactions, in particular. The importance of fission in astrophysics and for a wide variety of societal applications is established also.
Several probes have been proposed to study fission. In this presentation, we focus on the characterization of the fission-fragment products in terms of mass, charge and energy, and on their de-excitation. Recent experimental advances in the region of actinides and neutron- deficient lead are used to demonstrate the step forward in the field made from most accurate measurements. A consistent analysis of the information collected during the last years shows that the protons – which importance was overlooked so far, are key drivers of fission over the nuclear chart. A brief discussion of state-of-the-art models is finally proposed, emphasizing the necessary theoretical development regarding the dynamical transition from a fissioning-system- to a nascent-fragment-driven process.
