标题： Low temperature phase diagram of hydrogen at pressures up to 380 GPa. A possible metallic phase at 360 GPa and 200 K

摘要： 在参考文献1中，已在室温下发现了氢的两种新相：相IV在220 GPa以上，相V在约270 GPa以上。 在本工作中，我们在P~360 GPa和T<200 K条件下发现了一种新的相VI。从无特征的拉曼光谱、电阻的显著下降以及无光电导响应可推断该相可能是金属的。 我们利用拉曼、红外吸收和电测量方法在低温下研究了氢，在压力高达380 GPa的情况下，构建了氢的新相图。 显示英文摘要

摘要： Two new phases of hydrogen have been discovered at room temperature in Ref.1: phase IV above 220 GPa and phase V above ~270 GPa. In the present work we have found a new phase VI at P~360 GPa and T<200 K. This phase is likely metallic as follows from the featureless Raman spectra, a strong drop in resistance, and absence of a photoconductive response. We studied hydrogen at low temperatures with the aid of Raman, infrared absorption, and electrical measurements at pressures up to 380 GPa, and have built a new phase diagram of hydrogen.
