Ge已被研究到81 GPa的角色散衍射技术，使用图像板面积探测器和高亮度同步辐射从欧洲同步辐射设施。一个以前未知的相位的锗，与正交对称性的，被发现存在以上ensuremath{sim}75 GPa-之间的良好建立$ensuremath{η}$-TiN和简单六方相。此阶段与最近在$ensuremath{η}$-Sn和Si的简单六方相。
Ge has been studied to 81 GPa with angle-dispersive diffraction techniques, using an image-plate area detector and high-brilliance synchrotron radiation from the European Synchrotron Radiation Facility. A previously unknown phase of Ge, with orthorhombic symmetry Imma, is found to exist above ensuremath{sim}75 GPa---between the well established $ensuremath{eta}$-tin and simple hexagonal phases. This phase is the same as that found recently between the $ensuremath{eta}$-tin and simple hexagonal phases of Si.
