The radial distribution function and structure factor of liquid and amorphous gallium as described by the quasi-crystalline model

The far RDF oscillations and the main peak of the structure factor for liquid and amorphous gallium are described in terms of the quasi-crystalline model representing spatial correlations in liquids on the basis of a smeared crystal lattice. The initial lattice is a modified BCC lattice for liquid gallium and β-Ga structure for the amorphous state. The liquid gallium structure is inferred to be closely packed atoms complicated by their covalent coupling. Amorphous gallium has a microcrystalline structure with islets formed in a similar way as for β-Ga crystals.
