Diffraction of He atoms from Xe monolayer adsorbed on the graphite (0001) revisited: The importance of multiple scattering processes

TL;DR

This paper critically reexamines previous theoretical work on He atom diffraction from Xe monolayers on graphite, emphasizing the significance of multiple scattering processes and challenging earlier conclusions.

Contribution

It provides a detailed analysis showing that earlier findings are inconsistent with experimental data and highlights the importance of multiple scattering effects.

Findings

Previous conclusions are at variance with experimental evidence.

Multiple scattering processes are crucial for accurate modeling.

Revised calculations align better with observed data.

Abstract

We comment and discuss the findings and conclusions of a recent theoretical study of the diffraction of He atoms from a monolayer of Xe atoms adsorbed on the graphite (0001) surface [Khokonov et al., Surf. Sci. 496(2002)L13]. By revisiting the problem we demonstrate that all main conclusions of Khokonov et al. that pertain to the studied system are at variance with the available experimental and theoretical evidence and the results of multiple scattering calculations presented in this comment.
