“…On the experimental side, the M1 measurement requires dedicated techniques, because of the hindrance of the M1 transitions by the other competing modes. Nevertheless, the M1 response has been experimentally investigated using various probes, e.g., electrons, photons and hadrons [36][37][38][39][40][41][42]. These experimental data can provide a novel reference for theoretical frameworks and effective interactions employed, which have been optimized mainly only with the ground-state properties.…”

Magnetic dipole (M1) excitation is the leading mode of multi-nucleon excitations induced by the magnetic field, and is a phenomenon of the spin–orbit splitting and residual interactions involved. In this work, we investigate the effects of the residual interactions on the M1 excitation from a novel perspective, the framework of relativistic nuclear energy-density functional. The relativistic Hartree–Bogoliubov model is utilized to determine the nuclear ground state properties, while the relativistic quasi-particle random-phase approximation is employed for the description of M1-excitation properties. From the analysis of M1 mode in the Ca isotope chain, role of the isovector–pseudovector residual interaction is discussed. For open-shell nuclei, the pairing correlation also plays a noticeable role in the M1 mode. The experimental data on M1 mode is expected to provide a suitable reference to improve and optimize the theoretical models to describe the residual interactions.
