We study the dipole response associated with the Pygmy Dipole Resonance (PDR) and the Isovector Giant Dipole Resonance (IVGDR). in connection with specific properties of the nuclear effective interaction (symmetry energy and momentum dependence). in the neutron-rich systems 68Ni. 132Sn and 208Pb. https://allfixelectricales.shop/product-category/charging-stand/
