Abstract
The sensitivity of some properties of the isovector Giant Dipole Resonance on the neutron distribution of a nucleus such as 208Pb among others is studied within a set of modern Energy Density Functionals.The dipole response, measured in inelastic scattering of charged particles or real photons, is investigated via the small amplitude limit of the time-dependent Hartree and Hartree-Fock approaches --also known as Random Phase Approximation. How these observables correlate with the neutron skin thickness of the same nucleus and its connection with the density dependence of the nuclear symmetry energy will be discussed.
