Comment on High-Pressure Behavior of Hydrogen and Deuterium at Low Temperatures
arXiv:1901.05286 · doi:10.1103/PhysRevLett.122.199601
Abstract
X.-D. Liu et al. [Phys. Rev. Lett. 119, 065301 (2017)] report on the existence of a new unique solid phase of D2, which makes the high-pressure low-temperature behavior distinct from H2. Here, based on the analysis of their Raman data and phase transition theory, we show that the presented data do not support this claim.
