    "abstract": "We study low-lying multipole strength in neutron-halo nuclei. The strength\ndepends only on a few low-energy constants: the neutron separation energy, the\nasymptotic normalization coefficient of the bound state wave function, and the\nscattering length that contains the information on the interaction in the\ncontinuum. The shape of the transition probability shows a characteristic\ndependence on few scaling parameters and the angular momenta. The total E1\nstrength is related to the root-mean-square radius of the neutron wave function\nin the ground state and shows corresponding scaling properties. We apply our\napproach to the E1 strength distribution of 11Be.",
