To understand the response of very neutron rich nuclei to external fields, we study the E1 and E2 giant resonances in22O using a microscopic model i.e. the time-dependent density-matrix theory (TDDM). TDDM is an extension of the time-dependent Hartree-Fock theory to include two-body correlations and gives us a framework to study both the positions and widths of the giant resonances. It is found that the E1 and E2 strength distributions quite differ from those in stable nuclei due to the existence of excess neutrons.
