Description

Despite nearly 90 years since its discovery, the fission process remains a challenge for nuclear theories. Three main aspects have to be contemplated: the fission cross sections (probability that a fission occurs), the fission yields (distribution of the fragments resulting from the scission of the fissioning nucleus) and the fission fragments’ decay (responsible in particular of the prompt neutrons involved in the chain reaction).
Even if these three aspects are subject to important theoretical developments, this talk will focus on the calculation of the fission cross sections with a particular attention paid to the role played by nuclear level densities in the reaction modeling.
