Abstract

Bersohn proposed a model of two-dimensional 5p-electron delocalization for crystalline iodine, which was subsequently fully examined by Rosenberg. In the present work, this model is examined as a function of pressure, by generalizing Rosenberg’s assumptions. It is shown to afford a natural explanation for the formation of a quasi-two-dimensional system for pressures greater than 21 GPa, recently observed by Mössbauer spectroscopy.

APS and the Physical Review Editorial Office Continue to Support Researchers

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.

We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy.

Ways to Access APS Journal Articles Off-Campus

Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals. To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions.
