- Аннотация: Clustering effects show up in several ways along the Nuclear Chart. While for light nuclei (A≤40) the existence of clusters has been directly linked to nuclear structure and reaction dynamics observations, this is less the case when moving towards medium-mass systems. Pre-equilibrium emission is a nice example of mechanism capable to fill this gap, linking structure with dynamics and, eventually, to clustering in medium-mass nuclei. For central collisions, cluster pre-formation probabilities can be derived by studying light particle production cross sections and multiplicities. Several theories have been developed in the framework of exciton models to describe pre-equilibrium processes and try to explain how these are influenced by the structure of the reacting nuclei. The forthcoming availability of intense radioactive ion beams will open new challenging scenarios in this field of study, allowing the comparison of new systems where projectiles exhibit extreme neutron to proton ratios, bringing to structural configurations where clusters may show up in a more evident way.
