Interionic potentials in liquid metals including liquid noble and transition metals

Abstract

AbstractThe Born‐Green equation has been analyzed numerically to derive the effective interionic pair potentials from the structural data observed by X‐ray or neutron diffraction experiments for liquid metals (Mg, Zn, Hg, Al, Ga, In, Tl, Sn, Pb, Sb, Bi), noble metals (Cu, Ag, Au), and transition metals (Fe, Ni) using a linearized simultaneous equation method. In all cases the potentials were found to be insensitive to temperature and to have long‐ranged oscillations. But the damping behaviour of the oscillations for liquid Sb and Bi remarkably deviates from that of the usual metals such as liquid Na. For most metals, the wavelengths of oscillations observed in this work are in agreement with those expected from the electron theory of metals. The viscosity coefficient and surface tension were calculated. Adequate agreement with experiments was found.
