Isospin Symmetry Breaking in Mirror Nuclei 23Mg–23Na

摘要

Mirror energy differences (MED) are a direct consequence of isospinsymmetry breaking. Moreover, the study of MED has proved to give valuableinformation of several nuclear structure properties. We present theresults of an experiment performed in GANIL to study the MED in mirrornuclei 23Mg–23Na up to high spin. The experimental values are comparedwith state-of-the-art shell model calculations. This permits to enlightenseveral nuclear structure properties, such as the way in which the nucleonsalignment proceeds, the radius variation with J, the role of the spin-orbitinteraction and the importance of isospin symmetry breaking terms of nuclearorigin.
