    "abstract": "We present an analysis of two-proton shell gaps in Sn isotopes. As the\ntheoretical tool we use self-consistent mean-field models, namely the\nrelativistic mean-field model and the Skyrme-Hartree-Fock approach, both with\ntwo different pairing forces, a delta interaction (DI) model and a\ndensity-dependent delta interaction (DDDI). We investigate the influence of\nnuclear deformation as well as collective correlations and find that both\neffects contribute significantly. Moreover, we find a further significant\ndependence on the pairing force used. The inclusion of deformation plus\ncorrelation effects and the use of DDDI pairing provides agreement with the\ndata.",
