Comment on "experimental and theoretical study of the triple-differential cross section for electron-impact ionization of thymine molecules"

Abstract

In their recent paper, Bellm performed (e,2e) experiments on thymine at an incident energy of 250 eV. They wrote in the conclusion that a model based on the first Born approximation using the completely neglected differential overlap description is in very good agreement with the experimental data. On the contrary, we argue that this model fails to describe experiments on water performed at the same incident energy and is unable to explain any shift of the binary or recoil peaks. © 2012 American Physical Society.
