Abstract ： By using Heine-Abarencov pseudopotential method with mono-parameter rc , the expressions for ground state energy ε(rs ) , pressure P (rs ), and bulk modulus B(rs ) of metallic hydrogen (fcc, bcc, and hcp structures) are derived. Based on Gibbs free energy function criterion, the calculation shows that cold metallic hydrogen lattice (T = 0K) belongs to hcp structure.
