Explanation of the recent results on photoionization of endohedral atoms

TL;DR

This paper explains the discrepancy between experimental and theoretical results in photoionization of endohedral atoms, suggesting that ionization without fullerene shell excitation is highly unlikely, which clarifies previous inconsistencies.

Contribution

It provides a new explanation for the observed discrepancy by analyzing the probability of ionization without fullerene shell excitation.

Findings

Photoionization of caged atoms without shell excitation has low probability.

The discrepancy is due to the low likelihood of ionization without fullerene excitation.

Theoretical models need to account for shell excitation probabilities.

Abstract

We suggest an explanation of the recently observed discrepancy between the experimental and theoretical results on ionization of atoms, encapsulated into the fullerenes by photons with the energies of about 80-190eV. On the ground of previous theoretical considerations we conclude that the photoionization of the caged atom without excitation of the fullerene shell has low probability.
