| Popis: | The linear exp-6 isotherm is presented as an approach to the thermodynamic properties of liquid alkali metals over the whole liquid range including metal−nonmetal transition. The exp-6 pair interaction potential is applied to approach the underlying interplay between the characteristics soft repulsive interaction in dense, large attractive interaction in expanded liquid alkali metal and the observed thermodynamic properties. PVT of dense liquid alkali metals obey the linear exp-6 isotherm (Z − 1)V2 = A + Bρ-7/3 exp[α(1 − Cρ-1/3/rm) over the whole range of liquid densities, where Z is the compression factor, ρ = 1/V is the density, rm is the position of potential minimum, α is a parameter, and C is a constant. The intercept A and the slope B significantly are related to attraction and repulsion, respectively, and both depend on temperature. At the level of theory presented in this study, the thermodynamic effects caused by the polarization of atoms in expanded liquid alkali metals can be accounted for by e... |
