    "abstract": "The properties of the low-lying, collective 2+ states in neutron-rich oxygen\nisotopes are investigated in the framework of self-consistent microscopic\nmodels with effective Skyrme interactions. In RPA the excitation energies E2+\ncan be well described but the transition probabilities are much too small as\ncompared to experiment. Pairing correlations are then accounted for by\nperforming quasiparticle RPA calculations. This improves considerably the\npredictions of B(E2) values and it enables one to calculate more reliably the\nratios Mn/Mp of neutron-to-proton transition amplitudes. A satisfactory\nagreement with the existing experimental values of Mn/Mp is obtained.",
