    Abstract
  • In this paper, the metallic transformation pressure of solid hydrogen is calculated by using the simple metal Pseudopotential method, the possible structures of metallic hydrogen as well as the mechanical and thermal properties of this matter are investigated. The calculation shows that the transformation pressure is pt=465.95 GPa, at which the molecular state solid hydrogen (HCP structure) transforms into atomic phase metallic hydrogen (FCC structure) under absolute zero temperature condition.
