Comment on “The optimized mathematical treatment of the correct cutoff for integrals with the Rutherford scattering cross section” [Phys. Plasmas 32, 082207 (2025)]

Year: 2025

Type: article

Abstract: A recent paper by Chang suggests replacing the conventional expression for the Coulomb logarithm, that appears in charged particle scattering theory in weakly coupled plasmas, with a new and improved expression. In this comment, we demonstrate that the new expression is completely equivalent to the old one, and that any improvements are illusory.
