Abstract: (Elsevier)

We discuss theoretical studies of the Giant Dipole (GDR) and Giant Quadrupole (GQR) Resonances in nuclei far from stability, based on self-consistent Hartree–Fock and RPA calculations. The soft dipole mode that has been observed in light halo nuclei is predicted to diminish in skin nuclei, due to couplings to the isovector GDR. However, some low-lying dipole strength is predicted to exist in the isoscalar channel as a compression mode. The isoscalar GQR is expected to be much broader in skin nuclei than in stable nuclei, and substantial strength is predicted below the isoscalar GQR. The isovector GQR strength is spread over a wide range of excitation energies, both in skin and stable nuclei.
