Giant quadrupole resonances in ²⁰⁸Pb, the nuclear symmetry energy, and the neutron skin thickness

NUCLEAR STRUCTURE ²⁰⁸Pb; calculated strength functions, neutron and proton transition densities, excitation energies of isoscalar and isovector giant quadrupole resonance (ISGQR and IVGQR), neutron skin thickness, symmetry energy. Macroscopic approach based on quantal harmonic oscillator model, and microscopic approach based on nonrelativistic and covariant energy density functionals (EDF) within the RPA. Comparison with experimental data.
