In this work, we applied the nuclear shell model to study the energy levels for   54 54 26 28 Fe Ni & nucleus which contain two holes outside 56 28Ni core and occupy the 7 2 0f shell .In these calculations used computer program MatLab 2016 to calculate Modified Surface Delta Interaction (MSDI) is employed as a residual interaction. Comparison with experimental values and found to be rather good agreement.
