Description

In this talk I will discuss different theoretical analysis of some selected experimental data on low-energy nuclear observables --such as the dipole polarizability [1-3], the parity violating asymmetry [2-5] or the excitation energy of the Isobaric Analog State [6]-- that give access to the neutron skin thickness in medium and heavy nuclei. These measurements are complementary to the recent extraction of the neutron skin thickness using high-energy heavy ion collisions [7].
