Abstract摘要
The atomic nucleus is a quantum many-body system governed by the residual strong interaction, namely the nuclear force. Understanding its structure and decay properties requires the development of interaction and many-body models. Specifically, we need to study the strength of the nuclear force in a finite and in-medium nucleus and how to incorporate the most essential many-body correlations. Various nuclear structure models have thus been proposed. This report will first introduce the Configuration Interaction Shell Model based on phenomenological nuclear forces. It will then present my research, along with collaborators, on nuclear structure and decay properties using this model, including: establishing effective interactions to explain the properties of new isotopes and new isomeric states; exploring intruder states and isospin symmetry breaking resulting from cross-shell excitations and weakly-bound effects; integrating decay models and statistical methods for the research on (two) proton, neutron, -cluster emissions, as well as applications in nuclear safety. Finally, we will try to discuss the further development of the Configuration Interaction Shell Model, optimizing the isovector part of the nuclear force for describing medium-heavy nuclear regions with a unified phenomenological nuclear force, and trying to break through the exponential wall of quantum many-body systems based on physical correlations.
