Explanation of the recent results on photoionization of endohedral atoms

We suggest an explanation of the recently observed discrepancy between the experimental and theoretical results on ionization of atoms, encapsulated into the fullerenes, by photons with the energies of about $80$–$190$ eV. On the ground of previous theoretical considerations we conclude that for endohedrals the photoionization without emission of additional electrons or fullerenes shell atoms has a low probability even at such relatively low photon energies.
