    "abstract": "By means of HFB calculations with independent constraints on axial neutron\nand proton quadrupole moments Q_n and Q_p, we investigate the large amplitude\nisoscalar and isovector deformation properties of the neutron-rich isotope 20O.\nUsing the particle-number and angular-momentum projected Generator Coordinate\nMethod, we analyze the collective dynamics in the {Q_n, Q_p} plane. The\nparameterization SLy4 of the Skyrme interaction is used for all calculations in\nconnection with a density-dependent zero-range pairing interaction. Our results\nshow that already for this moderately neutron-rich nucleus the transition\nmoments are modified when independent neutron and proton collective dynamics\nare allowed.",
