Isospin-symmetry breaking in nuclear structure

摘要

The breaking of the isospin symmetry is discussed from the point of view of the nuclear shell-model. The accuracy of the theoretical framework is demonstrated on the description of the isobaric multiplet splittings. The use of phenomenological versus realistic interactions is discussed. We demonstrate the relevance of the theoretical description for isospin-forbidden processes. The developed formalism is important for the calculation of isospin-symmetry breaking corrections to the weak-interaction process on nuclei, and it can provide missing information on the structure of proton-rich nuclei relevant for astrophysics applications.
