Constraints on the symmetry energy and on neutron skins from the pygmy resonances in 68Ni and 132Sn

Andrea Carbone, Gianluca Coló, Angela Bracco +4

Correlations between the behavior of the nuclear symmetry energy, the neutron skins, and the percentage of energy-weighted sum rule (EWSR) exhausted by the Pygmy Dipole Resonance (…
