Popis: We construct a relativistic framework, charge and parity projected chiral mean field model, which takes into account explicitly a pion-exchange interaction. We take the chiral σ model Lagrangian for the construction of finite nuclei. We discuss several essential points of this framework with respect to explicit description of pionic-correlations, especially high-momentum component, in nuclear ground state wave function. We apply this framework to several even-even nuclei. We found that the pion contribution brings a significant change for nuclear ground state. We found that pion plays a role on the formation of jj-magic structure.
