Fission dynamics investigated in inverse kinematics in reactions induced by relativistic 236U projectiles

Resumo

Since its discovery in 1939, nuclear fission has represented one of the most intriguing processes in nuclear physics due to its complex theoretical description. In this work, we aim to contribute to a better understanding of fission studying its dynamics. For this, fission reactions induced by relativistic 236U projectiles in inverse kinematics are investigated. The large range of excitation energy and deformation covered by this nucleus make it very suitable to perform this kind of studies. The analysis of observables sensitive to the dynamics of the process will allow to constrain the value of the dissipation parameter responsible for coupling collective and intrinsic degrees of freedom and to investigate other significant features in the description of nuclear fission, such as the angular momentum gained by the fissioning system or the level densities of the deformed nuclei. We have also proposed to improve the experimental technique using (p,2p)-induced fission reactions to measure the excitation energy of the fissioning system.
