Comment on the Evidence of isostructural phase transitions in elemental zirconium

TL;DR

This paper critiques a recent study claiming no evidence for isostructural phase transitions in zirconium, emphasizing that such transitions are significant and have been observed in other elements like cerium.

Contribution

It challenges the conclusions of a recent publication, clarifying that isostructural phase transitions in zirconium are supported by experimental evidence and are of fundamental physics interest.

Findings

Isostructural phase transitions in zirconium are supported by experimental data.

Such transitions are only reported in cerium among metals.

The critique emphasizes the importance of these transitions in condensed matter physics.

Abstract

It is argued that the article by O.Bannon et al. ; High pressure stability of beta-Zr: no evidence for isostructural phase transitions, published recently -July 2021 - in High Pressure Research has no experimental foundation and the statement no evidence is absolutly misleading. Isostructural phase transition has been reported only in Ce metal, thus, the Beta-Zr to beta prime -Zr isostructural phase transitions has fundamental interest in condensed matter physics.
