The self-consistent mean spherical approximation for the one-component plasma

Effective Pair Potential ? Variational Thermodynamic Calculation of 4f Liquid Metals

“…Although the CHS reference system is a two-parameter system, the two parameters h and G are not in principle independent because CHS represents the MSA solution of the realistic OCP system [24]. We consider the parameters h and G to be related through MacGowan's criterion based on the self-consistency of MSA [26]. So free energy minimization together with MacGowan's criterion fix the unique values of h and G. The parameters along with the free energy values are depicted in Table 2 for five rare earth liquid metals at or near their melting prints.…”

“…In the absence of data for nE F for rare earth metals we have used the same for the corresponding solids [25]. S mag is the magnetic contribution and is estimated as [25] S mag k B ln 2J 1 X Now, using h and G as variational parameters and using MacGowan's self-consistent mean spherical approximation (SCMSA) criterion [26] we have for appropriate h and G…”
