Synopsis We developed a semi-phenomenological approach that permits to calculate the photoionization cross section of an endohedral A@C N . We take, along with the static pseudopotential of atom A and fullerene C N also the static and dynamic polarization of A and C N by the incoming photons and outgoing electrons. The approach is general and applicable to any spherically-symmetric endohedrals. Concrete results are obtained for Ar@C 60 and Xe@C 60 . We take into account the multi-electron correlations in the frame of the random phase approximation with exchange (RPAE).
