Comment on "Compton Scattering Spectrum for Si and Ge Systems", by Chen-Kai Qiao et al. DOI 10.1088/1361-6471/ab5e35

TL;DR

This paper critiques a 2020 study on Compton scattering spectra for Si and Ge, highlighting that its theoretical predictions were actually verified half a century earlier, questioning the novelty of the recent work.

Contribution

It clarifies the historical timeline of experimental verification for Compton scattering predictions, emphasizing prior validation that was overlooked.

Findings

Theoretical predictions from 2020 were experimentally verified 50 years ago.

The recent paper's claims of novelty are unfounded based on historical data.

Highlights the importance of thorough literature review in scientific research.

Abstract

It is pointed out that theoretical prediction in a paper published in 2020 were experimentally verified some 50 years ago.
