Title

Structure of hot ice VII

Abstract

We wish to investigate the structure of ice VII at high temperatures and pressures, i.e. 150 °C and 3-4 GPa. Preliminary neutron diffraction studies on D4 in 2010 by our team indicate that ice VII might not crystallize in the expected cubic Pn3m phase, but possibly to a “plastic phase” as predicted by various computer simulations. We think that the proposed experiment might make a significant contribution to the physics of ice.
