# Comments to the "Theory of Thomson scattering in inhomogeneous media"

## TL;DR

This paper highlights inconsistencies in the derivation of Thomson scattering spectra in inhomogeneous plasma, emphasizing the importance of a self-consistent kinetic theory that aligns with fundamental physical principles.

## Contribution

It points out the inconsistency in existing derivations and advocates for a self-consistent kinetic theory that correctly predicts spectral line asymmetry in inhomogeneous plasma.

## Key findings

- Inconsistency violates the Fluctuation-Dissipation Theorem
- Self-consistent kinetic theory predicts spectral line asymmetry
- Previous derivations deviate significantly from rigorous theory

## Abstract

In this short communication, we draw the readers' attention to the inconsistency in the derivation of the Thomson scattering spectrum in inhomogeneous plasma, which leads to violation of the Fluctuation-Dissipation Theorem and a substantial deviation from the results of the rigorous kinetic theory. Moreover, the self-consistent kinetic theory predicts the asymmetry of the spectral lines in inhomogeneous plasma.
