Abstract:
We explore various facets of Pygmy Dipole Resonance, including collectivity
and the role of the symmetry energy, by employing schematic models based on
separable interactions as well as transport descriptions based on Vlasov
equation. Experimental properties as energy centroid and sum-rules are
well reproduced. A mechanism for the appearance of Pygmy Dipole Resonance
and the development of the collectivity is proposed.
