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.8 pages, 2 figuresAtomic PhysicsAtomic and Molecular Clusterstext
