Query: Using a fluid cell model for description of a phase transition in simple
  liquid alkali metals   This article embraces a theoretical description of the first order phase
transition in liquid metals with application of a cell fluid model. The results
are obtained through calculation of the grand partition function without usage
of phenomenological parameters. The Morse potential is used for calculation of
the equation of state and the coexistence curve. Specific results for sodium
and potassium are obtained. Comparison of outcome of analytical expressions
with data of computer simulations is presented.
