Abstract:
The evolution of the properties of Pygmy Dipole Resonance and of Giant Dipole Resonance is investigated within a semi-classical transport model considering the Vlasov equation. For a chain of Ni isotopes the position of centroids, the Energy-Weighted Sum-Rule, the vibrational structure are obtained by employing an approach based on linear response. We evidence the role of the neutrons in in excess on
the excitation of low-lying dipole collective mode.
