    "abstract": "We discuss the systematics of the 2+ excitation energy and the transition\nprobability from this 2+ to the ground state for most of the even-even nuclei,\nfrom O16 up to the actinides, for which data are available. To that aim we\ncalculate their correlated J=0 ground state and J=2 first excited state by\nmeans of the angular-momentum and particle-number projected generator\ncoordinate method, using the axial mass quadrupole moment as the generator\ncoordinate and self-consistent mean-field states only restricted by axial,\nparity, and time-reversal symmetries. The calculation, which is an extension of\na previous systematic calculation of correlations in the ground state, is\nperformed within the framework of a non-relativistic self-consistent mean-field\nmodel using the same Skyrme interaction SLy4 and a density-dependent pairing\nforce to generate the mean-field configurations and mix them.",
