Polarizability exaltation of endofullerenes X@Cn (n = 20, 24, 28, 36, 50, and 60; X is a noble gas atom)

The polarizability exaltation in molecules of endohedral complexes of C₂₀, C₂₄, C₂₈, C₃₆, C₅₀, and C₆₀ fullerenes with He, Ne, Ar, and Kr noble gas atoms has been revealed and studied by the density functional theory method. It has been found that the sign of the Δα polarizability exaltation depends on the number of atoms in a fullerene molecule.
