Microscopic Studies Of Clustering In Light Nuclei

The nuclear shell model and the configuration interaction technique have long been pivotal in nuclear structure studies. However, their application to nuclear clustering presents significant challenges. Issues such as the separation of relative and intrinsic coordinates, the effective nature of particles and forces within the shell model, limitations of the configuration space, and connections to reaction observables are particularly complex. Additionally, the interaction between the quantum many-body system and the continuum of reaction states, especially near thresholds, profoundly affects clusterization properties and the broader nuclear many-body structure and dynamics.

 

In this presentation, I will outline our recent advancements in studying clustering using configuration interaction methods that stem from fundamental nucleon-nucleon interactions. The primary goal is to compare observed clustering properties in light nuclei with theoretical predictions and discuss the insights gained. Viewing the nuclear system as an open quantum system enhances our understanding of clustering dynamics and the emergence of collective degrees of freedom. Experimental validations of these phenomena will be highlighted.
