致密氢中新的低温相：phase diagram至421 GPa
New low temperature phase in dense hydrogen: The phase diagram to 421 GPa
摘要：
在寻求在低温下制造金属氢的过程中，人们发现了大量的新相，最高压力的相在室温附近有一些平坦的相线。我们已经研究了氢的静压GPa的金刚石压砧细胞和液氦的温度下，使用红外光谱。在GPa和T= 5K的压力下，我们发现了一个新相.虽然我们在可见光下观察到样品的强烈变暗，但我们没有证据表明该相是金属氢。
英文摘要：
In the quest to make metallic hydrogen at low temperatures a rich number of new phases have been found and the highest pressure ones have somewhat flat phase lines, around room temperature. We have studied hydrogen to static pressures of GPa in a diamond anvil cell and down to liquid helium temperatures, using infrared spectroscopy. We report a new phase at a pressure of GPa and T=5 K. Although we observe strong darkening of the sample in the visible, we have no evidence that this phase is metallic hydrogen.
