Microscopic reaction model for nucleon scattering on light nuclei


Nuclear reactions are an essential key for understanding the world around us. Their diversity (decay, particle scattering, fission ...)

and their complexity reflect the different dynamic aspects of the many-body problem. Modeling the underlying mechanisms that govern these

physical processes is a major challenge today, both for understanding the formation of the universe and its applications. For example,

the scattering reactions of nucleons on light nuclei such as Li, Be and B, are of interest in astrophysics: a better knowledge of the 7Be(n,p)7Li cross section, which is responsible for the disappearance of a large part of 7Be, could help to elucidate the problem encountered in cosmological models on the abundance of Li. Light nuclei are interesting and very special systems. They show complex correlations which give rise to very unusual structures, such as halos with one or more nucleons and aggregates of alpha particle type. The existence of such sub-structures plays an important role in the interaction between the projectile and the target and must have an impact on the reaction mechanisms and thus on cross section computation.
