Self-consistent mean-field models are nowadays well developed and provide a pertinent picture of nuclear properties throughout the whole mass table. We consider two different models, the Skyrme-Hartree-Fock approach (SHF) and the relativistic mean-field model (RMF). In our former investigations deformed calculations appear to be important for some observables like the 2-proton-shell-gap [1].
In our talk we want to show a possible correlation of the lowest, experimental measured 2+-state for Er-isotopes and their calculated deformed groundstate properties. The investigation in this region is of special interest since the measured data do not show the results that are naivly expected.
