Abstract
By means of HFB calculations with independent constraints on axial neutron and proton quadrupole moments and , we investigate the large amplitude isoscalar and isovector deformation properties of the neutron-rich isotope . Using the particle-number and angular-momentum projected generator coordinate method, we analyze the collective dynamics in the plane. The parametrization SLy4 of the Skyrme interaction is used for all calculations in connection with a density-dependent zero-range pairing interaction. Our results show that already for this moderately neutron-rich nucleus the transition moments are modified when independent neutron and proton collective dynamics are allowed.
