<Original Papers>Effective Interionic Potentials and Properties for Molten Iron, Cobalt and Nickel

Effective interionic potentials for molten iron, cobalt and nickel have been derived from the X-ray diffraction data obtained recently, using the Born-Green equation. In all cases, a long-range oscillatory type potential was confirmed. The observed wavelength of the oscillation applied to the discussion of the electron theory of metals, from which the effective valence number was estimated. The self-diffusion coefficient, viscosity coefficient and surface tension were calculated theoretically, and a reasonably good agreement with experimental data was determined
