• We present a density functional theory for hot dense plasmas, applicable to high Z atom, where electronic structure of atom as microscopic aspect and ionic distribution as macroscopic aspect are determined self-consistently. In this theory, the plasma is regarded as an ensemble of the virtual 'neutral atom' or, in other words, pseudo neutral atom. We apply our theory to Fe plasmas at temperatures T=100 eV and 1 keV in the density range 0.1ρ_<solid>〜200ρ_<solid> (ρ_<solid>=8.465×10^<22>cm^<-3>), neglecting the polarization of continuum electrons, and consequently obtain the result that the interatomic effective potential is almost the same as the bare-Coulomb type potential in one-component plasmas (OCP). From the obtained profile of the potential υ_<eff>(r)which determines bound electron states, we suggest a possibility of resonance states. The obtained internal energy for ion subsystem is lower than the Monte Carlo result for OCP, but the difference is within a few percent.
