Soviet Physics Journal Aims and scope

Abstract

The Gibbs thermodynamic potential is constructed for Li, Na, and K in the lattice vibration approximation with the aid of the Krasko-Gurskii model pseudopotential. The isothermal modulus of volume elasticity and its pressure derivative are calculated. Compression values are calculated from the equation of state dΦ/dΩ =0. The results obtained agree well with experiment.
