Conventional nuclear theory, based on the Schrodingcr equation, 1ms difficulties in explaining the binding energy differences of mirror nuclei [1,2]. The major Relativistic deformed mean-field calculation of binding energy contribution to the energy difference comes from the Coulomb force, and a variety of isospm differences of mirror nuclei breaking effects provide small contributions. The difficulty in reproducing the experimental values is kaown in the literature as the Okamofco-Nolen-Schiffer anomaly (ONSA). Several W. Koepf nuclear structure effects such as correlations, core polarization and isospin mixing have been School of Physics and Astronomy, Tel Aviv University, 69978 Ramat Aviv, Israel invoked to resolve the anomaly without success [3]. Since Okamoto and Pask [4] and Negele [5] suggested that the discrepancy could he G.
