Using ultrafast, time-resolved, 1.54 angstrom x-ray diffraction, thermal and ultrafast nonthermal melting of germanium, involving passage through nonequilibrium extreme states of matter, was observed. Such ultrafast, optical-pump, x-ray diffraction probe measurements provide a way to study many other transient processes in physics, chemistry, and biology, including direct observation of the atomic motion by which many solid-state processes and chemical and biochemical reactions take place.
利用超快、时间分辨的1.54埃X射线衍射，观察到锗的热熔化和超快非热熔化，其中涉及物质的非平衡极端状态。这种超快的光泵浦-X射线衍射探针测量提供了一种研究物理、化学和生物学中许多其他瞬态过程的方法，包括直接观察许多固态过程以及化学和生化反应发生时的原子运动。
