Abstract
The 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.

Es werden in alien Fallen temperaturunabhangige Potentiale vom langreichweitigen, oszillierenden Typ gefunden. Aber das Dampfungsverhalten der Oszillation von flussigem Antimon und Wismut weicht wesentlich von dem der normalen Metalle, wie dem des flussigen Na, ab. Die beobachtete Wellenlange der Oszillationen der anderen Metalle stimmt gut mit den aus der Elektronentheorie der Metalle erwarteten Werten uberein.
