The liquid structure is obtained by the thermodynamically self consistent liquid state theory, the variational modified hypernetted chain (VMHNC) approximation. It has been found that the calculated structural properties at the investigated thermodynamic states just above the melting point agree well with experiment. In this work we have determined the parameters of liquids Fe, Co and Ni for the universal choice of the evanescent core pseudopotentials of Fiolhais'. We have shown that this pseudopotential is transferable to the liquid state if used this parameterisation.en10.1080/003191002100043376info:eu-repo/semantics/closedAccessStatic Structure FactorPair Distribution FunctionPseudopotentialsPair PotentialsTransition-MetalsInterionic InteractionsThermodynamicsFeCoArticle405539552Q4WOS:0001790703000022-s2.0-0141484500Q3
