Abstract
The probability that photoionization of the caged atom in an endohedral
system is accompanied by excitation of the fullerene shell is shown to be
close to unity in broad intervals of the photoelectron energies. This
is obtained by summation of the perturbative series for the interaction
between the photoelectron and the fullerene shell. The result can be verified in
experiments.
As an outcome,
interaction between the photoelectron ejected from the cage atom and the
fullerene shell cannot be described by a static potential, since inelastic
processes become decisively important.
