Összefoglaló:
We will discuss manifestation of electron correlations in the processes of
interaction between low-intensity electromagnetic radiation with complex
atoms and endohedrals – atoms stuffed inside fullerenes. The electron
correlations essentially modify the cross-section of light-atom or
light-endohedral photoionization and photoexcitation. Specific feature of
electron correlations is the formation of different kinds of maxima and
minima that is manifested by the so-called Giant, confinement, interference
etc. resonances. They all are well observable in differential in energy and
angle of emitted electrons, and absolute cross-sections, as well as in the
probability of vacancies decay. Along with qualitative theoretical
considerations we will present results of numerical calculations performed
in the frame of the so-called random phase approximation with exchange
(RPAE). We will consider one-shell fullerene C60 , and two-shell fullerene
that represents C60 stuffed inside C240, C60@C240. As for the atoms, good
and illustrative objects are Argon and Xenon. At the end, we will discuss
the goals and perspectives of the research in this direction.
