Resumen en inglés

Up to now, empirical shell-model Hamiltonians for valence space calculations provide the most accurate description of the low-energy spectra and individual transitions of sd- and pf-shell nuclei. These features made them of particular importance for the description of the isospin-symmetry-breaking phenomena, such as energy splitting of the isobaric multiplets or isospin-forbidden transition rates. In this contribution, we demonstrate the applications of a recently constructed isospin non-conserving (INC) Hamiltonian in sd shell [Lam et al. Phys. Rev. C 87, 054304 (2013)]. First, we explore the partial decay scheme of 24Si and discuss the states affected by the Thomas-Ehrman shift. Second, we show the accuracy of the INC Hamiltonian for the description of the mirror energy differences.* The work is supported by the National Natural Science Foundation of China under Grant No. 11775277, the financial support to the “Théorie-ISB” project (IN2P3/CNRS, France), and the Ministry of Foreign Affairs and International Development of France in the framework of PHC Xu GuangQi 2015 under project No. 34457VA.< Leer menos
