    "abstract": "A nuclear structure model based on linear response theory (i.e., Random Phase\nApproximation) and which includes pairing correlations and anharmonicities\n(coupling with collective vibrations), has been implemented in such a way that\nit can be applied on the same footing to magic as well as open-shell nuclei. As\napplications, we have chosen to study the dipole excitations both in\nwell-known, stable isotopes like $^{208}$Pb and $^{120}$Sn as well as in the\nneutron-rich, unstable $^{132}$Sn nucleus, by addressing in the latter case the\nquestion about the nature of the low-lying strength. Our results suggest that\nthe model is reliable and predicts in all cases low-lying strength of non\ncollective nature.",
