Key Points

This comment addresses inaccuracies in the reported pair potentials due to formula errors in local-field corrections.
Analysis of the Farid local-field correction function's implementation.
Comparison of the corrected pair potentials with those from the Ichimaru–Utsumi LFCF.
Identified a misplacement in the coefficient formula leading to incorrect pair potentials.
Showed that corrected implementations of Farid and Ichimaru–Utsumi yield nearly identical results.

Implication

Comment uncovers errors in pair-potential calculations, indicating corrected local field corrections.

Abstract

This is a comment on Romman et al. [Appl. Phys. A 131, 828 (2025)]. We show that the anomalously deep pair-potential wells reported for the Farid local-field correction function are artifacts of a bracket misplacement in the coefficient formula. When correctly implemented, the Farid and Ichimaru–Utsumi LFCFs yield nearly identical pair potentials.
