  We study the possible occurrence of surface pion condensation in finite
nuclei in the relativistic mean field (RMF) theory. We are led to this
conjecture due to the essential role of pions in few-body systems and the
recent (p,n) experiments performed at RCNP for spin-isospin excitations of
medium and heavy nuclei. We calculate explicitly various N=Z closed shell
nuclei with finite pion mean field in the RMF framework and demonstrate the
actual occurrence of surface pion condensation.
