Quantum-statistical calculations of the thermodynamic properties of molybdenum at high energy densities

This paper is devoted to the theoretical investigation of the thermodynamic properties of molybdenum at condensed state (with densities rho >= rho(0) = 10.22 g/cm(3)) in the wide range of temperatures (T = 1-10(4) eV). Calculations of electron structure and electron contribution to equation of state were performed by three quantum-statistical models: the Thomas-Fermi, the Thomas-Fermi with quantum and exchange corrections and the Hartree-Fock-Slater ones. The contribution to thermal motion of ions and ion-ion interaction was taken into account in the framework of the Boltzmann ideal gas and the charged-hard-sphere models. Results of calculations were compared with available experimental data on shock compression and isentropic release of solid samples of molybdenum.
