Microscopic surface structure of liquid alkali metals
We report an x-ray scattering study of the microscopic structure of the surface of a liquid alkali metal. The bulk liquid structure factor of the eutectic K67Na33 alloy is characteristic of an ideal mixture, and so shares the properties of an elemental liquid alkali metal. Analysis of off-specular diffuse scattering and specular x-ray reflectivity shows that the surface roughness of the K-Na al...
متن کاملStructure and Packing Density of Liquid Metals
The diffraction pattern of molten metals shows several intensity-maxima, which can be interpreted in a similar way as the Debye-Scherrer pattern of crystalline powders. For this purpose, however, it is necessary to introduce liquid-like distortions. Such an approach has been given by the concept of paracrystallinity [1] , which contains the well known equations of crystallography [2] as limitin...

متن کاملRadial band structure of electrons in liquid metals.
The electronic band structure of a liquid metal was investigated by measuring precisely the evolution of angle-resolved photoelectron spectra during the melting of a Pb monolayer on a Si(111) surface. We found that the liquid monolayer exhibits a free-electron-like band and it undergoes a coherent radial scattering, imposed by the radial correlation of constituent atoms, to form a characteristi...
متن کاملFreezing of simple liquid metals
Freezing of simple liquid metals and the relative stabilities of competing crystalline solids are investigated using thermodynamic perturbation theory, the interactions between ions being modeled by eective pair potentials derived from pseudopotential theory. The ionic free energy of the solid phase is calculated, to ®rst order in the perturbation potential, using classical density-functional ...
