The reliability of the revised potential is supported by a comparison the neutral pseudoatom potential at several thermodynamic states. Although the single-step VMHNC inversion yields acceptable results for the characteristic features of the density dependence of the revised potentials for liquid lithium, the difference in the medium behaviour of the Li potential is a cause of concern. This discrepancy and the limitations of the approximate theories in the inverse calculations have been discussed with the possible improvements.eninfo:eu-repo/semantics/closedAccessLiquid LithiumInverse MethodEffective PotentialsVariational Modified Hypernetted Chain TheoryMolecular-Dynamics SimulationHypernetted-Chain EquationRare-Earth-MetalsAlkali-MetalsBridge FunctionStructural DataAlloysThermodynamicsMixturesModelsArticle63865874Q2WOS:0002241052000172-s2.0-5044223265Q4
