Comment on: "Investigating the time dependence of neutron-proton equilibration using molecular dynamics simulations" by A.Jedele et al: Phys Rev C 107, 024601 (2023)

TL;DR

This paper critiques a previous study on neutron-proton equilibration in nuclear collisions, highlighting issues with the use of simulation models and interpretations of results.

Contribution

It provides a critical analysis of the application and interpretation of the COMD model in neutron-proton equilibration studies.

Findings

Identifies misinterpretations in the original analysis.

Highlights improper use of the COMD model.

Emphasizes the need for careful model application.

Abstract

In this paper, the authors discuss neutron-proton equilibration process induced on the 70Zn + 70Zn system at 35 MeV/nucleon, comparing experimental results with the Anti-symmetrized Molecular Dynamics and the Constrained Molecular Dynamics model simulations (COMD). The comment contains observations on the improper use of the COMD model, including some misinterpretations of the obtained results.
