Description
Our study investigates the response of neutron-rich nickel and tin isotopes under a dipole excitation, with emphasis on the properties of the Pygmy Dipole Resonance (PDR), the Giant Dipole Resonance (GDR) and the role of the symmetry energy. Using a framework based on Random Phase Approximation with Separable Interactions (RPA-SI), applying linear response theory and the Migdal model, we study the evolution of dipole polarizability across the two chains isotopes, comparing them with experimental data, and we analyze the pygmy mode`s contribution to the dipole polarizability.
