Abstract
We have demonstrated that the polarization of the fullerene
shell considerably alters the
polarization potential of an atom, stuffed inside a fullerene. This
essentially affects the electron
elastic scattering phases as well as corresponding cross-sections. We
illustrate the general trend by
concrete examples of electron scattering upon endohedrals
Ne@C60 and Ar@C60.
To obtain the presented results, we have suggested a simplified
approach that permits to
incorporate the effect of fullerenes polarizability into the
Ne@C60 and
Ar@C60 polarization
potential. By applying this approach, we obtained numeric results that
show strong variations in
shape and magnitudes of scattering phases and cross-sections due to
effect of fullerene
polarization upon the endohedral polarization potential.
