Query: On the modification of the photoionization of subvalent subshells in
  endohedral noble gas atoms   It is demonstrated that outer and inner electron shells, including that
formed by collectivized electrons of the fullerene C60, affects dramatically
the cross section of the subvalent ns-subshells of the noble gas endohedral
atoms A@C60. The calculations are performed within the framework of a very
simple, so-called "orange skin", model that makes it possible, in spite of its
simplicity, to take into account the modification of the ns-subshell due to its
interaction with inner and outer atomic shells, as well as with the
collectivized electrons of the C60. As a concrete example, we consider the Xe
5s electrons completely collectivized by the powerful action of the Xe close
and remote multi-electron neighboring shells.
