The all-electron full-potential linearized muffin-tin orbital method, by means of quasi-harmonic Debye model, is applied to investigate the elastic constant and thermodynamic properties of body-centered-cubic tantalum (bcc Ta). The calculated elastic constants of bcc Ta at 0 K is consistent with the previous experimental and theoretical results. Our calculations give the correct trends for the pressure dependence of elastic constants. By using the convenient quasi-harmonic Debye model, we refined the thermal equations of state. The thermal expansivity and some other thermal properties agree well with the previous experimental and theoretical results.

The effective ion–ion interaction for sodium is calculated from a fundamental basis, using a one-orthogonalized plane wave (OPW) bare electron – ion matrix element, and the Geldart and Taylor electron gas screening function. Particular attention is paid to the form of the interaction for asymptotically large ion–ion separation, and it is shown that this interaction varies approximately as the fifth power of the ion–ion separation in the region in which the amplitude of the potential is appreciable. The elastic constants, cohesive energy, and the specific heats of body-centered cubic (b.c.c.) and close-packed sodium are shown to be in excellent agreement with experiment. The equilibrium and stability of the model sodium lattice described by the proposed potential are discussed, and it is concluded that the potential can be used tentatively in a fundamental calculation of atomic properties of defects.
