摘　　要：The purpose of this work is to apply the fully consistent RRPA method to the collective giant resonance of nuclei far from the p-stability line. The isovector giant dipole resonance in Ca isotopes is investigated in the framework of the fully consistent RRPA. The calculations are performed in an effective Lagrangian with a parameter set NL3, which was proposed for satisfactorily describing nuclear ground state properties as well as the isospin giant monopole resonance, i.e. nuclear breathing mode. The response functions of IVGDR for various Ca isotopes are plotted in Fig.1. The solid and dotted curves are full RRPA and unperturbed strengths, respectively. The dashed curves represent
