To explain the unexpected trend, changes of the nuclear structure far-off stability have been suggested, namely a quenching of the N = 82 shell gap already in 130Cd, only two proton holes away from doubly magic 132Sn. We study the behaviour of the 2+ energies in the Cd isotopes from N = 50 to N = 82, i.e. across the entire span of a major neutron shell using modern beyond mean field techniques and the Gogny force. We demonstrate that the observed low 2+ excitation energy in 128Cd close to the N = 82 shell closure is a consequence of the doubly magic character of this nucleus for oblate deformation favoring thereby prolate configurations rather than spherical ones. © 2008 Elsevier B.V.
