Simple and Onion-type Fullerenes shells as resonators and amplifiers

TL;DR

This paper explores how single and double fullerene shells influence photoionization and vacancy decay in atoms enclosed within them, revealing modifications in cross-sections and decay probabilities due to electron scattering and polarization effects.

Contribution

It introduces a detailed analysis of fullerene shells as resonators and amplifiers affecting atomic processes, supported by numerical calculations with C60, C240, Ar, and Xe.

Findings

Fullerene shells cause additional structures in photoionization cross-sections.

Fullerene shells modify vacancy decay probabilities.

Electron scattering and polarization are key mechanisms affecting these processes.

Abstract

We discuss the influence of a single or double fullerenes shell upon photoionization and vacancy decay of an atom, stuffed inside the fullerenes construction. The main manifestations of this influence are additional structures in the photoionization cross-section and variation of the vacancy decay probability. The main mechanisms, with which fullerenes shells affect the processes in caged atoms is the scattering of the outgoing electrons by the fullerenes shell and modification of the photon beam due to fullerenes shell polarization. General consideration will be illustrated by numeric calculations where C60 and C240 will be chosen as fullerenes and Ar and Xe as caged atoms.
