    "abstract": "Role of pairing correlation for emergence of low-frequency vibrational\nexcitations in neutron drip line nuclei is discussed paying special attention\nto neutrons with small orbital angular momentum l. Self-consistent pairing\ncorrelation in the Hartree-Fock-Bogoliubov (HFB) theory causes the change of\nthe spatial structure of the quasiparticle wave functions; \"the pairing\nanti-halo effect\" in the lower component and \"the broadening effect\" in the\nupper component. The resultant spatial distribution of the two-quasiparticle\nstates among low-l neutrons, \"the broad localization\", brings about\nqualitatively new aspects, especially the large transition strength of the\nlow-frequency vibrational excitations in nuclei close to the neutron drip line.\nBy performing HFB plus quasiparticle random phase approximation (QRPA)\ncalculation for the first 2+ states in neutron rich Ni isotopes, the unique\nrole of self-consistent pairing correlation is pointed out.",
