Numerical results for the density of electron states for expanded liquid mercury are presented in the density range from 13.55 to 5.0 g cm −3 . The calculations are based on a single‐site effective medium approximation for the muffin‐tin model of a liquid metal. The energy‐dependent effective medium is determined from a generalized Wigner‐Seitz condition. The gap between the 6s and 6p states occurs at ∂ = 5.6 g cm −3 , in good agreement with nonrelativistic band‐structure calculations for hypothetical forms of crystalline mercury.
