Abstract:
We investigate within a generalized Brown-Bolsterli model, with extended separable interactions, the properties of Pygmy Dipole Resonance and of Giant Dipole Resonance. We derive the optimal values for the
coupling constants appearing in the residual interaction and discuss their
meaning in connection to the density dependence of symmetry energy.
