TL;DR
This paper investigates the shell structure of cesium layers on C60 fullerenes using a mean-field model, aligning theoretical predictions with experimental ionization energies and magic numbers.
Contribution
It introduces a spherical mean-field potential model tailored for Cs-coated fullerenes, calibrated to experimental data, to analyze their electronic shell structure.
Findings
Reproduces experimental ionization energies of Cs(N) clusters
Identifies magic numbers consistent with photo-ionization spectra
Provides a theoretical framework for shell corrections in coated fullerenes
Abstract
Strutinsky shell corrections for the Cesium-coated fullerenes were investigated. The single particle levels of electrons are obtained using the spherical mean-field potential of a shifted Wood-Saxon type. The parameters of the potential are adjusted to reproduce the experimental ionization energies of the Cs(N) clusters and the magic numbers observed in their photo-ionization spectra of the C60Cs(N) aggregates.
