Relativistic random-phase-approximation description of M1 excitations with the inclusion of π mesons

NUCLEAR STRUCTURE ⁴⁸Ca, ⁹⁰Zr, ²⁰⁸Pb; calculated GT^- and M1 strength distributions, magnetic dipole resonance features, B(GT), B(M1), EWSR for M1 transitions, transitions configurations. ⁴⁸Ca; calculated proton and neutron single-particle spectra. Random-phase approximation (RPA) based on the relativistic mean-field (RMF) theory, using the density-dependent effective interactions with contribution of π mesons included as residual interaction. Comparison with experimental values.

Pseudospin symmetry restoration and the in-medium balance between nuclear attractive and repulsive interactions

NUCLEAR STRUCTURE ⁴⁸Ca, ⁹⁰Zr, ¹³²Sn, ²⁰⁸Pb, ³¹⁰126; calculated Proton shell gaps and the splittings of the neighboring pseudospin symmetry (PS) partners using RMF Lagrangians PKA1, PKO3, and the RMF ones DD-ME2, PK1, NL3*, and compared with available experimental data. ²⁰⁸Pb; calculated contributions to the binding energy from various channels given by the RHF Lagrangian PKA1, proton pseudospin orbital (PSO) splittings using PKA1, PKO3, DD-ME2, and the tentative parametrizations. Relativistic Hartree-Fock (RHF) approach.
