The bulk moduli of the Na-K, Na-Cs, and K-Rb liquid equiatomic alloys at T=373 K are calculated by the variational method with the hard-sphere reference system. The local Animalu-Heine model pseudopotential and Toigo-Woodruff exchange-correlation function are used for the calculation. A good agreement with experimental data is achieved.

The Wills-Harrison pair interaction is investigated for liquid Fe on the base of the introduced relation between parameters of the model pseudopotential and d-electron characteristics. It is shown that the procedure suggested leads to the significant shift of the first minimum of the pair potential and increases the softness of its repulsive part.

The SW-MSA Calculation of Self-Diffusion Coefficients in Liquid Lithium and Rubidium

Successfully used recently for liquid Na and K the approach combined the linear trajectory approximation with the square-well model in the semi-analytical representation of the mean spherical approximation to calculate the self-diffusion coefficients is applied here to liquid Li and Rb. As well as earlier for Na and K, the results obtained are found to be in reasonable agreement with the available experimental data and confirm previous conclusion that the square-well model within the mean spherical approximation is quite useful for description of diffusion properties in liquid alkali metals.
