Giant dipole resonance in atomic nuclei

Giant dipole resonance is a collective excitation of atomic nuclei. In the macroscopic interpretation giant dipole resonance is a collective oscillation of all protons against all neutrons in a nucleus. Giant dipole resonance occurs systematically in most nuclei with energies typically in the range of 10–30 MeV. GDR is an efficient tool to probe nuclear properties, for study of structure and dynamics of atomic nuclei, nuclear reaction mechanism.
