Abstract
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.
