Neutron diffraction patterns from liquid antimony have been obtained at 660 and 800 "C. The structure factors are nearly independent of temperature. Comparing the results with the structure of liquid bismuth and the hard sphere model the existence of two structure types in liquid antimony previously indicated seems t o be ambiguous. The electrical resistivity was calculated using Ziman's theory [ 121 and compared with experimental data. From this in the case of liquid antimony the invalidity of the Born approximation in Ziman's theory was found.Neutronenbeugungsbilder von fliissigem Antimon wurden bei 660 und 800 "C beobachtet. Die gefundenen Strukturfaktoren sind nahezu unabhangig von der Temperatur. Aus dem Vergleich mit der Struktur des flussigen Wismuts und dem Hard-Sphere-Modell kann nicht aufdie Koexistenz von zwei Strukturtypen in flussigem $ntimon, aufdie bisher hingewiesen wurde, geschlossen werden. Die Berechnung des elektrischen Widerstands nach der Zimanschen Theorie [12] und der Vergleich r.it experimentellen Daten wurden durchgefiihrt. Daraus wurde die Ungiiltigkeit der Bornschen Approximation in der Zimanschen Theorie fur flussiges Antimon gefunden.

“…Samples were heated in a boron nitride (BN) crucible ( 3 0 x 2 0 mm2) and in an Ar-lO% H, atmosphere in the high-temperature camera as shown in Fig. 1 [5]. Before each run the sample was heated to 700 "C, where the oxide was reduced by the atmosphere used, and then brought to the desired temperature within *5 "C. The crucible size made it possible to obtain a fairly flat surface area, about lox 10 mm2, regardless of the surface tension of the metal under investigation.…”

X-ray diffraction patterns have been obtained from liquid metals (Al, Ga, In, TI, Pb, Sn, Bi) near the melting point. After calculating the structure factor (Fourier analysis), the atomic radial distribution function was evaluated from which interatomic distance and coordination number were obtained. It has been shown that the ratio (K,/K,) of the position of the first peak ( K , ) to that of the second peak (K,) in the structure factor is a very useful parameter to represent the structure of liquid metals.Rontgenbeugungsbilder von flussigen Metallen (Al, Ga, In, T1, Pb, Sn, Bi) wurden in der Nahe dea Schmelzpunktes beobachtet. Durch eine schon mehrfach dargestellte Methode (Fourier-Analyse) wurde der Strnktnrfaktor in eine radiale Atomverteilungsfunktion transformiert, aus der sich der mittlere Abstand nachster Atome und die Koordinationszahl ergeben. Es wurde gezeigt, da13 das Verhaltnis (K2/Kl) der Lage des ersten Maximums (Kl) zii der des zweiten Maximums (&) i m Strnkturfaktor eiu niitzlicher Parameter zur Beschreibung der Struktur von flussigen Metallen ist.

“…The strong correlation between the data obtained from the two methods is apparent. The energyscanning result has been compared also with recent existing data* (Black & Cundall, 1965;Wagner, Ocken & Joshi, 1965;Ocken & Wagner, 1966;Rivlin, Waghorne & Williams, 1966;Halder & Wagner, 1967Caputi, Rodriquez & Pings, 1968;Waseda & Suzuki, 1970;Ruppersberg & Reiter, 1972). Both the peak positions and the value of si(s) at each peak correlate well.…”

Quantitative liquid-structure analysis using energy-scanning diffraction rather than the traditional angle-scanning diffraction is introduced. In the experimental method, white radiation and a solid-state detector are employed. This new method is inherently faster and less beset with problems of experimental instability than are angular-scanning methods. However, many differences in analysis are introduced. In particular, measurement of the primary beam spectrum, the nature of the absorption and dispersion corrections, details of the polarization correction, the ranges of the atomic scattering factor and of the incoherent scattering term, and the mating of different scattering regimes all require special consideration. Application of the new instrumental method and the reconstructed analytical procedure to liquid mercury at room temperature has produced a result in agreement with other recent studies.
