My work consists in studying the nucleon scattering off a target nucleus using as a starting point the effective nucleon-nucleon interaction interaction of Gogny. It is a question of building the interaction between the incident nucleon and the target nucleon: the optical potential. This work is based on the numerous works concerning the mean-field and beyond mean-field methods developed in the of the lab. We also develop the associated computational tools for the treatment of the scattering problem in the case of non-local optical potentials.
