第一个结果的系统研究冰的拉曼散射和X射线衍射在兆巴范围内的报告。我们的讨论，这是基于冰的动力学特征及其相图，重点是可能出现的对称状态（冰X）。得出的结论是，在62 GPa以上，质子的离域发生沿着O−O方向和冰可能是对称的统计观点。
First results on a systematic study of ice by Raman scattering and X-ray diffraction in the megabar range are reported. Our discussion, which is based on the dynamical features of ice and its phase diagram, focuses on the possible occurrence of a symmetric state (ice X). It is concluded that above 62 GPa, delocalization of the proton occurs along O−O directions and ice may be symmetric from the statistical viewpoint.
