Multipole excitation phenomena in exotic nuclei are investigated within the framework of the fully self‐consistent Relativistic Quasi‐particle Random‐Phase Approximation (RQRPA) based on the Relativistic Hartree‐Bogoliubov (RHB) model with density dependent meson‐nucleon couplings, and finite‐range Gogny interaction to account for the pairing correlations. The RHB+RQRPA study of nuclei towards the proton drip‐line indicates the appearance of an exotic collective excitation mode: the proton pygmy dipole resonance, due to oscillations of loosely bound protons against the rest of nucleons. The continuum RPA using Skyrme interactions is employed in a study of doubly magic 48 Ni, resulting in a rather broad distribution of the low‐lying dipole strength, due to the coupling to the continuum.
